The exposed pigment particles are also naked to damaging ultraviolet light, which can compromise pigment permanency. Watercolor paint is traditionally and Watercolor painting still commonly applied with brushes, but modern painters have experimented with many other implements, particularly sprayers, scrapers, sponges or sticks, painting and have combined watercolors with pencil, charcoal, crayon, chalk, ink, Watercolor painting engraving, monotype, lithography and collage, or with acrylic paint. Many watercolor painters, perhaps uniquely among all modern visual artists, still adhere to prejudices dating from the 19th century Guernica painting rivalry between transparent and bodycolor painters. Synthetic brushes tend to dump too much of the paint bead at the beginning of Watercolor painting the brush stroke and leave a larger puddle of paint when the brush is lifted from the paper, and they cannot compete with the pointing of natural sable brushes and are much less durable.

Moist paper will cause the scumbled color to diffuse slightly before it dries. When using Watercolor painting watercolors, it is important to use the full range of paint consistency. Indeed, as a matter of economy, convenience or technique, painters have often preferred palettes comprising the smallest practical selection of paints. The smallest practical palette consists of one dark neutral paint, typically including a carbon black pigment or, in works before 1800, a sepia ink.

By contrast, watercoloring was also valued by surveyors, mapmakers, military officers and engineers for its usefulness in depicting properties, terrain, fortifications or geology in the field and for illustrating public works or commissioned projects. These vary greatly from manufacturer to manufacturer. These designations are only relative; the CP paper from one manufacturer may be rougher than the R paper from another manufacturer.

It is based on the three traditional subtractive primary colors (red, yellow and blue), each in a warm and cool version (specific pigments listed as examples for each color choice): This selection was advocated so that bright or saturated mixtures could be produced by related primary colors, e.g. Unlike oil or acrylic painting, where the paints essentially stay where they are put and dry more or less in the form they are applied, water is an active and complex partner in the watercolor painting process, changing both the absorbency and shape of the paper when it is wet and the outlines and appearance of the paint as it dries.

These numbers refer to the size of the brass brushmakers mould used to shape and align the hairs of the tuft before it is tied off and trimmed, and as with shoe lasts, these sizes vary from one manufacturer to the next. As art markets continue to expand, painting societies continue to add members and aging Baby Boomers increasingly retire to more contemplative hobbies, watercolors seem poised to enter yet another golden age . Watercolor paint consists of four principal ingredients: The term watermedia refers to any painting medium that uses water as a solvent and that can be applied with a brush, pen or sprayer; this includes most inks, watercolors, temperas, gouaches and modern acrylic paints.

On the other hand they are typically much cheaper than natural hair, and the best synthetic brushes are now very serviceable; they are also excellent for texturing, shaping, or lifting color, and for the mechanical task of breaking up or rubbing paint to dissolve it in water. A high quality sable brush has five key attributes: pointing (in a round, the tip of the tuft comes to a fine, precise point that does not splay or split; in a flat, the tuft forms a razor thin, perfectly straight edge); snap (or spring ; the tuft flexes in direct response to the pressure applied to the paper, and promptly returns to its original shape); capacity (the tuft, for its size, holds a large bead of paint and does not release it as the brush is moved in the air); release (the amount of paint released is proportional to the pressure applied to the paper, and the paint flow can be precisely controlled by the pressure and speed of the stroke as the paint bead is depleted); and durability (a large, high quality brush may withstand decades of daily use). Most natural hair brushes are sold with the tuft cosmetically shaped with starch or gum, so brushes are difficult to evaluate before purchasing, and durability is only evident after long use. Many artists now prefer synthetic brushes because of their superior points and durability. There is no market regulation on the labeling applied to artists brushes, but most watercolorists prize brushes from kolinsky (Russian or Chinese) sable.

Evenly wetted, machinemade papers typically curl along one dimension, revealing the curvature of the cylinder they were formed on; some mouldmade papers and all handmade papers cockle in a random, uneven pattern. Wildlife illustration reached its peak in the 19th century with artists such as John James Audubon, and today many naturalist field guides are still illustrated with watercolor paintings. Several factors contributed to the spread of watercolor painting during the 18th century, particularly in England.

White paint (titanium dioxide PW6 or zinc oxide PW4) is best used to insert highlights or white accents into a painting. To make paper, the cellulose is wetted, mechanically macerated or pounded, chemically treated, rinsed and filtered to the consistency of thin oatmeal, then poured out into paper making moulds.

The cumulative effect is objective, textural and highly controlled, with the strongest possible value contrasts in the medium. The marketing name for a paint, such as cobalt blue or emerald green , is often only a poetic color evocation or proprietary moniker; there is no legal requirement that it describe the pigment that gives the paint its color.

The main point is to take advantage of the complete range of paint effects that are produced at different paint consistencies. Tube paints are normally used with a flat palette that provides compartmentalized paint wells (for holding separate paint colors) and a large mixing area for mixing or diluting paints; pan paints are arrayed in enameled metal paint boxes that provide shallow mixing areas in the folding cover or in a fold out faceted tray. The difficulty in watercolor painting is almost entirely in learning how to anticipate and leverage the behavior of water, rather than attempting to control or dominate it. Many difficulties occur because watercolor paints do not have high hiding power, so previous efforts cannot simply be painted over; and the paper support is both absorbent and delicate, so the paints cannot simply be scraped off, like oil paint from a canvas, but must be laboriously (and often only partially) lifted by rewetting and blotting.

Among the most popular are: A single brush can produce many lines and shapes. Internal sizing is added to the paper pulp after rinsing and before it is cast in the paper mould; external or tub sizing is applied to the paper surface after the paper has dried.

In Chinese, Korean, and Japanese painting it has been the dominant medium, often in monochrome black or browns. The content designations 100% cotton or 100% cotton rag have little significance to the actual quality or handling attributes of the paper.

Modern acrylic paints are based on a completely different chemistry that uses water soluble acrylic resin as a binder. Watercolor painters before c.1800 had to make paints themselves using pigments purchased from an apothecary or specialized colourman ; the earliest commercial paints were small, resinous blocks that had to be wetted and laboriously rubbed out in water. His method of developing the watercolor painting in stages, starting with large, vague color areas established on wet paper, then refining the image through a sequence of washes and glazes, permitted him to produce large numbers of paintings with workshop efficiency and made him a multimillionaire in part through sales from his personal art gallery, the first of its kind.

Modern watercolor paints are now as durable and colorful as oil or acrylic paints, and the recent renewed interest in drawing and multimedia art has also stimulated demand for fine works in watercolor. The 19th century claim that transparent watercolors gain luminosity because they function like a pane of stained glass laid on paper Watercolors appear more vivid than acrylics or oils because the pigments are laid down in a more pure form with fewer fillers (such as kaolin) obscuring the pigment colors.

However, as with paints, modern chemistry has developed many synthetic and shaped fibers that rival bristle and even hair for softness and flexibility. This often induces in student painters a pronounced and inhibiting anxiety about making an irreversible mistake.

The goal is to build up or mix the paint colors with short precise touches that blend to avoid the appearance of pointilism. Botanical artists have always been among the most exacting and accomplished watercolor painters, and even today watercolors—with their unique ability to summarize, clarify and idealize in full color—are used to illustrate scientific and museum publications.

As dark colors also require inconvenient mixing, most painters prefer to add a premixed dark neutral paint containing a carbon (black) pigment and a tinting pigment to produce a slight color bias, usually sold under the marketing names indigo, payne s gray, neutral tint or sepia. A final consideration is lightfastness, or the ability of a pigment to retain its original color appearance under exposure to light. William Blake published several books of hand tinted engraved poetry, illustrations to Dante s Inferno, and also experimented with large monotype works in watercolor. From the late 18th century through the 19th century, the market for printed books and domestic art contributed substantially to the growth of the medium.

Handmade papers typically have four natural deckles (feathery, uneven edges) left by the paper mould; mouldmade papers have two natural deckles along the edges of the web, and two simulated deckles produced by cutting the sheet with a jet of compressed water; machinemade papers have no deckles. In the 19th century, before modern high quality and heavy weights of paper were available, watercolor painters preferred to stretch papers before painting on them, to minimize or eliminate cockling and to provide a firm painting support. Usually one part tube paint must be diluted with 2 to 3 parts water to eliminate bronzing in paint applied with a large brush to dry paper; with 4 to 6 parts water to produce the most saturated color; and with still more water to produce delicate tints of color and to enhance pigment textures (granulation or flocculation).

The confluence of these cultural, engineering, scientific, tourist and amateur interests culminated in the celebration and promotion of watercolor as a distinctly English national art . To ensure this, colors are mixed by picking up the desired quantity of dissolved paint from the prewetted paint well, using a moist, clean brush, then applying the paint onto the flat mixing area of the palette.

In Europe, gorgeous landscape and maritime watercolors were produced by Paul Signac, and Paul Cézanne developed a watercolor painting style consisting entirely of overlapping small glazes of pure color. Among the many 20th century artists who produced important works in watercolor, mention must be made of Wassily Kandinsky, Emil Nolde, Paul Klee, Egon Schiele and Raoul Dufy; in America the major exponents included Charles Burchfield, Edward Hopper, Charles Demuth, Elliot O Hara, Alice Schille and above all John Marin, 80% of whose total output is in watercolor. Brushes are typically the most expensive component of the watercolorist s tools, and a minimal general purpose brush selection would include: Reputable watercolor brush manufacturers include DaVinci, Escoda, Isabey, Raphael, Kolonok, Robert Simmons and Winsor & Newton.

Watercolor artists were commonly brought with the geological or archaeological expeditions funded by the Society of Dilettanti (founded in 1733) to document discoveries in the Mediterranean, Asia and the New World. Finally, papers are also sold as watercolor blocks -- a pad of 20 or so sheets of paper, cut to identical dimensions and glued on all four sides, which provides high dimensional stability and portability, though block papers tend to have subdued finishes.

Watercolors were the used as the basic document from which collectible landscape or tourist engravings were developed, and handpainted watercolor originals or copies of famous paintings contributed to many upper class art portfolios. In particular, the graceful, lapidary and atmospheric genre paintings by Richard Parkes Bonington created an international fad for watercolor painting, especially in England and France, in the 1820s. The popularity of watercolors stimulated many innovations, including heavier and more heavily sized wove papers and brushes (called pencils ) manufactured expressly for watercolor painting.

Watercolor has a longstanding association with drawing or engraving, and the common procedure to curtail such mistakes is to make a precise, faint outline drawing in pencil of the subject to be painted, to use small brushes, and to paint limited areas of the painting only after all adjacent paint areas have completely dried. Another characteristic of watercolor paints is that the carbohydrate binder is only a small proportion of the raw paint volume, and much of the binder is drawn between the hydrophilic cellulose fibers of wet paper as the paint (and paper) dries. As this single paint can only communicate value gradations from full strength (dark) to white paper, it produces monochrome images, often supplemented and sharpened by an underdrawing or additions in pen and ink. A familiar choice is the primary palette consisting of a magenta (traditionally but inaccurately identified as red ), yellow and cyan (traditionally blue ) paint, each representing a subtractive primary color.

Watercolor tutorials were first published in this period by Varley, Cox and others, innovating the step-by-step painting instructions that still characterizes the genre today; The Elements of Drawing , a watercolor tutorial by the English art critic John Ruskin, has been out of print only once since it was first published in 1857. Bodycolor is a watercolor made as opaque as possible by a heavy pigment concentration, and gouache is a watercolor made opaque by the addition of a colorless opacifier (such as chalk or zinc oxide).

Each technique has its purpose—the first provides color accuracy (for photorealist painting), the second provides color variety (especially in dark colors), the third produces many wet in wet effects between wetter and drier paint areas (for greater color expressiveness), the fourth can produce a variety of luminous, iridescent or broken color effects, similar to mixtures with pastel chalks. Third, watercolors should be used confidently: applied with a single stroke or joined strokes, then left alone to dry. Paints with low hiding power are valued because they allow an underdrawing or engraving to show in the image, and because colors can be mixed visually by layering paints on the paper (which itself may be either white or tinted).

In the late 18th century, the English cleric William Gilpin wrote a series of hugely popular books describing his picturesque journeys throughout rural England and illustrated with his own sentimentalized monochrome watercolors of river valleys, ancient castles and abandoned churches; his example popularized watercolors as a form of personal tourist journal. Though commercial watercolor brands typically include up to 100 or more paint colors in tubes, subtractive pigment mixtures can produce a complete range of colors from a small number of specific paints.

This is customarily achieved by using natural hair harvested from farm raised or trapped animals, in particular sable, squirrel or mongoose. Many watercolor painters still stretch their papers, but because natural deckles are appreciated today for their decorative, handmade effect, the modern preference is to work on unstretched papers, either by using a heavier weight of paper, by allowing paper to dry out before it becomes too saturated, or by exploiting the artistic effects that cockling can produce. Watercolor painting has the reputation of being quite demanding; it is more accurate to say that watercolor techniques are unique to watercolor.

The glazing method also works exceptionally well in watercolor portraiture, allowing the artist to depict complex flesh tones effectively. Wet in wet includes any application of paint or water to an area of the painting that is already wet with either paint or water. The absorbency of a paper is assessed by licking it.

In industrial paper production, the pulp is formed by large papermaking machines that spread the paper over large cylinders—either heated metal cylinders that rotate at high speed (machinemade papers) or wire mesh cylinders that rotate at low speed (mouldmade papers). Unfortunately, paint manufacturer lightfastness ratings are not always trustworthy.

This increases the scattering of light from both the pigment and paper surfaces, causing a characteristic whitening or lightening of the paint color as it dries. Major 19th century American exponents of the medium included William Trost Richards, Fidelia Bridges, Thomas Moran, Thomas Eakins, Henry Roderick Newman, John LaFarge, John Singer Sargent and, preeminently, Winslow Homer. Watercolor was less popular on the Continent, though many fine examples were produced by French painters, including Eugène Delacroix, François Marius Granet, Henri-Joseph Harpignies and the satirist Honore Daumier. Unfortunately the careless and excessive adoption of brightly colored, petroleum derived aniline dyes (and pigments compounded from them), which all fade rapidly on exposure to light, and the efforts to properly conserve the 20,000 Turner paintings inherited by the British Museum in 1857, led to an examination and negative re-evaluation of the permanence of pigments in watercolor.

Pan paints (actually, small dried cakes or bars of paint in an open plastic container) are usually sold in two sizes, full pans (approximately 3 cc of paint) and half pans (favored for compact paint boxes). The resulting color will changed depending on the layering order of the pigments.

However, the art materials industry is far too small to exert any market leverage on global dye or pigment manufacture. The lightest color is obtained by using paint heavily diluted with water, or applied to the paper and then blotted away with a paper towel.

Most watercolor papers sold today are in the range between 280gsm to 640gsm. As with papers and paints, it is common for retailers to commission brushes under their own label from an established manufacturer.

Papers that are dense and made from heavily macerated pulp have a bright, metallic rattle, while papers that are spongy or made with lightly macerated pulp have a muffled, rubbery rattle. All papers obtain a texture from the mould used to make them: a wove finish results from a uniform metal screen (likea window screen); a laid finish results from a screen made of narrowly spaced horizontal wires separated by widely spaced vertical wires. The most stable painting medium is pastel, but modern lightfast watercolors are now more stable than oil or acrylic mediums.

This leads to a more equal spacing of paints around the hue circle, and the inclusion of a green paint. Fabriano even offers a soft press (SP) sheet intermediate between CP and HP. Watercolor papers are traditionally sized, or treated with a substance to reduce the cellulose absorbency.

In fact, there are very few genuinely transparent watercolors, neither are there completely opaque watercolors (with the exception of gouache); and any watercolor paint can be made more transparent simply by diluting it with water. Paint pigments and formulations vary across manufacturers, and watercolor paints with the same color name (e.g., sap green ) from different manufacturers can be formulated with completely different ingredients. Watercolor paints are customarily evaluated on a few key attributes.

Despite the common misconception, there is no visual difference between the viscous paint packaged in tubes and the dried paints in pans. To remedy this confusion, in 1990 the art materials industry voluntarily began listing pigment ingredients on the paint packaging, using the common pigment name (such as cobalt blue or cadmium red ), and/or a standard pigment identification code, the generic color index name (PB28 for cobalt blue, PR108 for cadmium red) assigned by the Society of Dyers and Colourists (UK) and the American Association of Textile Chemists and Colorists (USA).

The painter simply works on the exposed sheet and, when finished, uses a knife to cut the adhesive around the four sides, separating the painting and revealing the fresh paper underneath. Finally, the best art papers are designated archival, meaning they will last without significant deterioration for a century or more. Satirical broadsides by Thomas Rowlandson, many published by Rudolph Ackermann, were also extremely popular. The three English artists credited with establishing watercolor as an independent, mature painting medium are Paul Sandby (1730-1809), often called the father of the English watercolor , Thomas Girtin (1775-1802), who pioneered its use for large format, romantic or picturesque landscape painting, and Joseph Mallord William Turner (1775-1851), who brought watercolor painting to the highest pitch of power and refinement and created with it hundreds of superb historical, topographical, architectural and mythological paintings.

Typically, this might be a light blue wash for the sky. India, Ethiopia and other countries also have long traditions.

The term watercolor refers to paints that use water soluble, complex carbohydrates as a binder. If mixed with other pigments, white paints may cause them to fade or change hue under light exposure.

(A wide range of papers using alternative plant fibers, some of them not archival, are available from Asian manufacturers; some watercolor painters even employ sheets of printable plastic, sold under brand names such as Yupo.) A useful test of paper quality is simply to burn a small piece of the paper in an ashtray: pure cellulose completely burns away to a wispy, whitish gray ash. Among notable early practitioners of watercolor painting were Van Dyck (during his stay in England), Claude Lorrain, Giovanni Benedetto Castiglione, and many Dutch and Flemish artists.

The last technique requires the first layer to be a highly diluted consistency of paint; this paint layer dissolves the surface sizing of the paper and loosens the cellulose tufts in the pulp. The California Water Color Society, founded in 1921 and later renamed the National Watercolor Society, sponsored important exhibitions of their work.

The highly absorbent papers that contain no sizing are designated waterleaf. Most art papers are sold as single sheets of paper in standard sizes. Armand. The traditional furnish or material content of watercolor papers is cellulose, a structural carbohydrate found in many plants.

Glazes are used to mix two or more colors, to adjust a color (darken it or change its hue or chroma), or to produce an extremely homogenous, smooth color surface or a controlled but delicate color transition (light to dark, or one hue to another). The stability of the paper (amount of cockling when soaked) and its response to lifting paint (the paper should not shred or tear) is best tested by making a painting on it. All cellulose fibers absorb moisture and expand along the length of the fiber when wet; this produces the familiar buckling or warping called cockling.

This is usually indicated as a numerical rating, from I (high lightfastness) to III or IV (low lightfastness), on the paint tube or in the paint technical information available from the manufacturer. Among the most widely used brands of commercial watercolors today are Daniel Smith, Daler Rowney, DaVinci, Holbein, Maimeri, M.

The California painters exploited their state s varied geography, Mediterranean climate and automobility to reinvigorate the outdoor or plein air tradition; among the most influential were Phil Dike, Millard Sheets, Rex Brandt, Dong Kingman and Milford Zornes. These include: aureolin (PY40), alizarin crimson (PR83), genuine rose madder (NR9), genuine carmine (NR4), genuine vermilion (PR106), most naphthol reds and oranges, all dyes (including most liquid watercolors and marker pens), and paints premixed with a white pigment, including paints marketed under the names naples yellow, emerald green or antwerp blue.

Most of these are colorants invented in the 19th century or before that have been superseded by far more durable modern alternatives, and these are usually sold as hue paints (e.g., alizarin crimson hue is a modern pigment that resembles alizarin crimson). Commercial paintmaking brands appeared and paints were packaged in metal tubes or as dry cakes that could be rubbed out (dissolved) in studio porcelain or used in portable metal paint boxes in the field.

Less staining colors can be lightened or removed almost entirely when wet, or when rewetted and then lifted by stroking gently with a clean, wet brush and then blotted up with a paper towel. Staining is increased if the paint manufacturer uses a dispersant to reduce the paint milling (mixture) time, because the dispersant acts to drive pigment particles into crevices in the paper pulp, dulling the finished color. Granulation refers to the appearance of separate, visible pigment particles in the finished color, produced when the paint is substantially diluted with water and applied with a juicy brush stroke; pigments notable for their watercolor granulation include viridian (PG18), cerulean blue (PG35), cobalt violet (PV14) and some iron oxide pigments (PBr7).

Artists typically have a few favorites and do most work with just one or two brushes. Often it is impossible to distinguish a good drybrush watercolor from a color photograph or oil painting, and many drybrush watercolors are varnished or lacquered after they are completed to enhance this resemblance. Scumbling (in the 19th century, called crumbling color or dragging color ) is an unrelated technique of loading a large, moist flat or round brush with concentrated paint, wicking out the excess, then lightly dragging the side or heel of the tuft across the paper to produce a rough, textured appearance, for example to represent beach grass, rocky surfaces or glittering water.

Most common is the full sheet (22 x 30 ), and half sheets (15 x 22 ) or quarter sheets (15 x 11 ) derived from it. The traditional sizing has been gelatin, gum arabic or rosin, though modern synthetic substitutes (alkyl-ketene dimers such as Aquapel) are now used instead.

Botanical illustrations became popular in the Renaissance, both as hand tinted woodblock illustrations in books or broadsheets and as tinted ink drawings on vellum or paper. Fine watermedia papers are manufactured under the brand names Arches, Fabriano, Hahnemuehle, Lanaquarelle, Saunders Waterford, Strathmore, Winsor & Newton and Zerkall; and there has been a recent remarkable resurgence in handmade papers, notably those by Twinrocker, Velke Losiny, Ruscombe Mill and St.

The primary palette is therefore useful to demonstrate that compactness also affects convenience (the difficulty involved in mixing any common color) and color saturation (generally, the paint mixture gamut or total number of unique colors it is possible to mix with a palette). The amount of texture that can be produced depends on the finish or tooth of the paper (R or CP paper works best), the size of the brush, the consistency and quantity of the paint in the brush, and the pressure and speed of the brush stroke.

In fact, many superb paintings flout some or all of these guidelines, and they have little relevance to modern painting practice. Perhaps only with the exception of egg tempera, watercolor is the painting medium that artists most often compound themselves, by hand, using raw pigment and paint ingredients purchased from retail suppliers and prepared using only kitchen utensils. Flats may be designated either by a similar but separate numbering system, but more often are described by the width of the ferrule, measured in centimeters or inches. In general, natural hair brushes have superior snap and pointing, a higher capacity (hold a larger bead, produce a longer continuous stroke, and wick up more paint when moist) and a more delicate release.

Watercolor (US) or watercolour (UK) and also aquarelle, from French, is a painting method. Contemporary breakthroughs in chemistry made many new pigments available, including prussian blue, ultramarine blue, cobalt blue, viridian, cobalt violet, cadmium yellow, aureolin (potassium cobaltinitrite), zinc white and a wide range of carmine and madder lakes.

As a result the mixture of any two paints adjacent on the hue circle usually produces the most saturated color mixtures for every hue between them (specific pigments listed as examples for each color choice): Both the split primary and hexachrome palettes obtain dull or darkened colors, including a neutral (dark gray or black), by mixing together paints or colors on opposite sides of the hue circle—especially orange or scarlet with cyan, and carmine or magenta with green. As a matter of convenience, painters typically also add one or more paints made with an iron oxide pigment (the so called earth pigments) and sold under the marketing names yellow ochre, raw sienna, raw umber, burnt sienna, burnt umber and/or venetian red. As a result, watercolor paints do not form an enclosing layer of vehicle around the pigment particles and a continuous film of dried vehicle over the painting support, but leave pigment particles scattered and stranded like tiny grains of sand on the paper.

In this period American watercolor (and oil) painting was often imitative of European Impressionism and Post-Impressionism, but significant individualism flourished within regional styles of watercolor painting in the 1920s to 1940 s, in particular the Cleveland School or Ohio School of painters centered around the Cleveland Museum of Art, and the California Scene painters, many of them associated with Hollywood animation studios or the Chouinard Art Institute (now California Institute of the Arts). Archival means that the papers are made entirely of high alpha cellulose or 100% cotton or linen fiber (that is, they are lignen free, as lignen causes the darkening and embrittlement under light exposure), pH neutral (meaning there is no residual acidity left from the chemical processing of the pulp), buffered (a small quantity of an alkaline compound, usually calcium carbonate, is added to the furnish to neutralize the effect of atmospheric acids), and free of any artificial paper brighteners or whiteners (e.g., ultraviolet dyes).

In the partisan debates of the 19th century English art world, gouache was emphatically contrasted to traditional watercolors and denigrated for its high hiding power or lack of transparency ; transparent watercolors were exalted. The paper edges were fixed with gummed tape, starch glue or tacks, and the paper was left to dry.

Less expensive brushes, or brushes designed for coarser work, may use horsehair or bristles from pig or ox snouts and ears. Both types of machine produce the paper in a continuous roll or web, which is then cut into individual sheets. The basis weight of the paper is a measure of its density and thickness.

Larger (and less standardized) sheets include the double elephant (within an inch or two of 30 x 40 ) and emperor (40 x 60 ), which are the largest sheets commercially available. The traditional and most common support for watercolor paintings is paper; other supports include papyrus, bark papers, plastics, vellum or leather, fabric, wood, and canvas.

A round for example, can create thin and thick lines, wide or narrow strips, curves, and other painted effects. Modern commercial watercolor paints are available in two forms: tubes or pans.

Lightfastness is a crucial issue with watercolors, because the paint pigment is not surrounded by a protective dried binder (as in oil or acrylic paints) but is left exposed on the surface of the paper. In handmade papers, the pulp is hand poured ( cast ) into individual paper moulds (a mesh screen stretched within a wood frame) and shaken by hand into an even layer.

Multiple layers of watercolor do achieve a very luminous effect because of less fillers obscuring the pigment particles. Staining is another characteristic assigned to watercolor paints: a staining paint is difficult to remove or lift from the painting support after it has been applied or dried. First, the raw or pure paint in the paint wells should never be discolored with any other paint.

In the past decade or so, each nylon bristle now has many small hairs off of it, each of which can hold a drop of water. Color muddiness or dullness typically comes from excessively brushing wet paint after it has been applied to the paper, or adding new layers of paint onto paper that has soaked water into its pulp (capillary action draws the paint inside the paper, dulling the color, rather than letting it dry on the surface).

Papers are also manufactured in rolls, up to about 60 wide and 30 feet long. (The previous Imperial system, expressed as the weight in pounds of one ream or 500 sheets of the paper, regardless of its size, obsolete in some areas, is still used in the United States.) Watercolor papers are typically almost a pure white, sometimes slightly yellow, though many tinted or colored papers are available.

This allows artists to choose paints according to their pigment ingredients, rather than the poetic labels assigned to them by marketers. It is described as the gram weight of one square meter of a single sheet of the paper, or grams per square meter (gsm).

This contrasts with the trend in commercial paints to suppress pigment textures in favor of homogeneous, flat color. Commercial watercolor paints come in two grades: Artist (or Professional ) and Student . However, because they have been demonstrated to be impermanent in watercolors, certain pigments (paints) should never be used under any circumstances.

The mechanical strength of the paper is assessed by repeatedly folding it back and forth along a single crease. Once all paints are on the mixing area, they are mixed and/or applied to the painting. Second, colors can be mixed in at least four ways: (1) by completely mixing together on the palette the paints that exactly match a desired color; (2) by loading together in a large brush the separate paints that approximately match the desired color, then letting these partially mix as the paint is applied to the paper; (3) by laying down first a single paint color, then dropping in the remaining paint colors with the brush while the painted area is still wet; (4) by glazing the paints as separate layers, one over another.

Paint manufacturers buy very small supplies of these pigments, mill (mechanically mix) them with the vehicle, solvent and additives, and package them. Many artists are confused or misled by labeling practices common in the art materials industry. Painters who use this technique may apply 100 glazes or more to create a single painting.

Industry labeling practice is to include a lightfastness rating on the paint packaging, and painters should only use paints that have a lightfastness rating of I or II under the testing standards published the American Society of Testing and Materials (now ASTM International). . Student grade paints have less pigment, and often are formulated using two or more less expensive pigments.

The paper was first completely immersed in water for 10–15 minutes, then laid completely flat on a board. The best of these hairs have a characteristic reddish brown color, darker near the base, and a tapering shaft that is pointed at the tip but widest about halfway toward the root.

This method is currently very popular for painting high contrast, intricate subjects, in particular colorful blossoms in crystal vases brightly illuminated by direct sunlight. This is normally done to define the large areas of the painting with irregularly defined color, which is then sharpened and refined with more controlled painting as the paper (and preceding paint) dries. Wet in wet actually comprises a variety of specific painting effects, each produced through different procedures.

The only notable difference is that some tube paints, such as viridian or cerulean blue, produce a gritty, uneven paint mixture when left to dry and then rewetted. There are three finesses to color mixtures with watercolors. The tuft is a bundle of animal hairs or synthetic fibers tied tightly together at the base; the ferrule is a metal sleeve that surrounds the tuft, gives the tuft its cross sectional shape, provides mechanical support under pressure, and protects from water the glue joint between the trimmed, flat base of the tuft and the lacquered wood handle, which is typically shorter in a watercolor brush than in an oil painting brush, and also has a distinct shape—widest just behind the ferrule and tapering to the tip.

Among the elite and aristocratic classes, watercolor painting was one of the incidental adornments of a good education, especially for women. An important school of watercolor painting in Germany was led by Hans Bol (1534–1593) as part of the Dürer Renaissance. Despite this early start, watercolors were generally used by Baroque easel painters only for sketches, copies or cartoons (small scale design drawings).

Originally (16th to 18th centuries) watercolor binders were sugars and/or hide glues, but since the 19th century the preferred binder is natural gum arabic, with glycerin and/or honey as additives to improve plasticity and dissolvability of the binder, and with other chemicals added to improve product shelf life. The wax or oil mediums repel, or resist the watercolor paint.

Graham, Schmincke, Talens (Rembrandt), and Winsor & Newton. Thanks to modern industrial organic chemistry, the variety, saturation (brilliance) and permanence of artists colors available today is greater than ever before. Its portability makes it ideal for plein air painting, and painters today can buy compact watercolor kits—containing a dozen or more pan paints, collapsible brushes, water flask, brush rinsing cup and fold out mixing trays—that fit neatly into a coat pocket. Basic watercolor technique includes washes and glazes.

Flocculation refers to a peculiar clumping typical of ultramarine pigments (PB29 or PV15). Among the important and highly talented contemporaries of Turner and Girtin were John Varley, John Sell Cotman, Anthony Copley Fielding, Samuel Palmer, William Havell and Samuel Prout.

When painting, painters typically hold the brush just behind the ferrule for the smoothest brushstrokes. Brushes hold paint (the bead ) through the capillary action of the small spaces between the tuft hairs or fibers; paint is released through the contact between the wet paint and the dry paper and the mechanical flexing of the tuft, which opens the spaces between the tuft hairs, relaxing the capillary restraint on the liquid. This water-soluble color pencil allows to draw fine details and to blend them with water. Watercolor pastel allow to draw bigger details than watercolor pencil, and to fill quickly large surface with lot of pigments. Most watercolor painters before c.1800 had to use whatever paper was at hand: Thomas Gainsborough was delighted to buy some paper used to print a Bath tourist guide, and the young David Cox preferred a heavy paper used to wrap packages.

White paint will always appear dull and chalky next to the white of the paper, however this can be used for some effects. A brush consists of three parts: the tuft, the ferrule and the handle. Camel is sometimes used to describe hairs from several sources (none of them a camel). Natural and synthetic brushes are sold with the tuft shaped for different tasks.

The painter can use wax crayons or oil pastels prior to painting the paper. The majority of paints sold are in collapsible metal tubes in standard sizes (typically 7.5, 15 or 37 ml.), and are formulated to a consistency similar to toothpaste.

In general, wet in wet is one of the most distinctive features of watercolor painting and the technique that produces a striking painterly effect. The essential idea is to wet the entire sheet of paper, laid flat, until the surface no longer wicks up water but lets it sit on the surface, then to plunge in with a large brush saturated with paint. Until fairly recently, nylon brushes could not hold a reservoir of water at all so they were extremely inferior to natural bristles.

Artist quality paints are usually formulated less fillers (kaolin or chalk) which results in richer color and vibrant mixes. the brightest orange is the mixture of a yellow with some red in it (warm yellow) and a red with some yellow in it (warm red); the brightest green is the mixture of a yellow with some blue in it (cool yellow) with a blue with some yellow in it (cool blue).

In East Asia, watercolor painting with inks is referred to as brush painting or scroll painting. (A Scottish Society of Painters in Water Colour was founded in 1878.) These societies provided annual exhibitions and buyer referrals for many artists and also engaged in petty status rivalries and esthetic debates, particularly between advocates of traditional ( transparent ) watercolor and the early adopters of the denser color possible with bodycolor or gouache ( opaque watercolor).

This caused a sharp decline in their status and market value. Subsequent layers are applied at increasingly heavier concentrations, always using a small round brush, only after the previous paint application has completely dried.

Variegated washes, which blend two or more paint colors, can also be used, for example as a wash with areas of blue and perhaps some red or orange for a sky at sunrise or sunset. A glaze is the application of one paint color over a previous paint layer, with the new paint layer at a dilution sufficient to allow the first color to show through. Generally, paint directly from the tube should be used only with drybrush application: if the paint is used to completely cover the paper it typically dries to a dull, leathery appearance (called bronzing).

Fingerpainting with watercolor paints originated in China. Although watercolor painting is extremely old, dating perhaps to the cave paintings of paleolithic Europe, and has been used for manuscript illumination since at least Egyptian times but especially in the European Middle Ages, its continuous history as an art medium begins in the Renaissance. White paint (gouache) mixed with a transparent watercolor paint will cause the transparency to disappear and the paint to look much duller.

Each new layer is used to refine the color transitions or to efface visible irregularities in the existing color. Both effects display the subtle effects of water as the paint dries, are unique to watercolors, and are deemed attractive by accomplished watercolor painters.

An important diagnostic is the rattle of the paper, or the sound it makes when held aloft by one corner and shaken vigorously. The German Northern Renaissance artist Albrecht Dürer (1471-1528) who painted several fine botanical, wildlife and landscape watercolors, is generally considered among the earliest exponents of the medium.

Bristle brushes are stiffer and lighter colored. Among these are injunctions never to use white paint, never to use black paint, only to use transparent color, or only to work with primary color mixtures.

Squirrel hair is quite thin, straight and typically dark, and makes tufts with a very high liquid capacity; mongoose has a characteristic salt and pepper coloring. Exactly the same brown or ochre colors can be matched with either of the six paint palettes, but it is tedious to do.

The finish is also affected by the methods used to wick and dry the paper after it is couched (removed) from the paper mold or is pulled off the papermaking cylinder. Watercolor papers come in three basic finishes: hot pressed (HP), cold press (CP, or in the UK Not , for not hot pressed ), and rough (R). Watercolor painters typically paint on paper specifically formulated for watermedia applications.

Pans are historically older but commonly perceived as less convenient; they are most often used in portable metal paint boxes, also introduced in the mid 19th century, and are preferred by landscape or naturalist painters. In general a #12 round brush has a tuft about 2 to 2.5 cm long; tufts are generally fatter (wider) in brushes made in England than in brushes made on the Continent: a German or French #14 round is approximately the same size as an English #12.

The brush tip must be wetted but not overcharged with paint, and the paint must be just fluid enough to transfer to the paper with slight pressure and without dissolving the paint layer underneath. With rare exceptions, all modern watercolor paints utilize pigments that were manufactured for use in printing inks, automotive and architectural paints, wood stains, concrete, ceramics and plastics colorants, consumer packaging, foods, medicines, textiles and cosmetics.

Although the rise of abstract expressionism, and the trivializing influence of amateur painters and advertising or workshop influenced painting styles, led to a general decline in the popularity of watercolor painting after c.1950, watercolors continue to be utilized by important artists such as Joseph Raffael, Andrew Wyeth, Philip Pearlstein, David Remfry, Eric Fischl, Gerhard Richter, Cecily Byk and Francesco Clemente. Even with commercially prepared paints, watercolor is prized for its nontoxic, tap ready solvent; lack of odor or flammability; prompt drying time; ease of cleanup and disposal; long shelf life; independence from accessory equipment (jars, rags, easels, stretchers, etc.).

Artist and Professional paints are more expensive but many consider the quality worth the higher cost. As there is no transparent white watercolor, the white parts of a watercolor painting are most often areas of the paper reserved (left unpainted) and allowed to be seen in the finished work. However, botanical and wildlife illustrations are perhaps the oldest and most important tradition in watercolor painting.

The late Georgian and Victorian periods produced the zenith of the British watercolor, among the most impressive 19th century works on paper, by Turner, Varley, Cotman, David Cox, Peter de Wint, William Henry Hunt, John Frederick Lewis, Myles Birket Foster, Frederick Walker, Thomas Collier and many others. Watercolors acquired in the 19th century a market reputation for relative impermanence that continues to suppress their price today, and painters who admire this medium will make choices to improve its market status: in fact, lightfast watercolor paints on archival papers are more durable than any oil painting on canvas.

A flat brush when used on end can produce thin lines or dashes in addition to the wide swath typical with these brushes, and its brushmarks display the characteristic angle of the tuft corners. The size of a round brush is designated by a number, which may range from 0000 (for a very tiny round) to 0, then from 1 to 24 or higher. This palette is nearly always justified with the specious argument that paints are impure carriers of primary color , a misunderstanding of subtractive color mixture that appears in Michel-Eugene Chevreul s Simultaneous Color Harmony and Contrast published in 1839. A modern approach to the six paint palette (trademarked in the printing industry as a hexachrome palette) jettisons the impure paint rationalization and simply focuses on obtaining the largest gamut from a limited selection of available pigments.

Transparent colors do not have titanium dioxide (white) or most of the earth pigments (sienna, umber, etc.) which are very opaque. A watercolor is the medium or the resulting artwork, in which the paints are made of pigments suspended in a water soluble vehicle.

In fact, the staining characteristics of a paint depend in large part on the composition of the support (paper) itself, and on the particle size of the pigment. The densest possible color is obtained by using the paint as it comes from the tube.

James Whatman first offered a wove watercolor paper in 1788, and the first machinemade ( cartridge ) papers from a steam powered mill in 1805. All art papers can be described by eight attributes: furnish, color, weight, finish, sizing, dimensions, permanence and packaging. Nevertheless, isolated exponents continued to prefer and develop the medium into the 20th century.

Because thinned watercolor paint is far less viscous than oil or acrylic paints, the brushes preferred by watercolor painters have a softer and denser tuft. This method is useful to produce transitions in value or color within narrow bands, such as the locks of hair in a portrait head. At the other extreme from wet in wet techniques, Drybrush is the watercolor painting technique for precision and control, supremely exemplified in many botanical paintings and in the drybrush watercolors of Andrew Wyeth.

The Swiss painter Louis Ducros was also widely known for his large format, romantic paintings in watercolor. The confluence of amateur activity, publishing markets, middle class art collecting and 19th century painting technique led to the formation of English watercolor painting societies: the Society of Painters in Water Colours (1804, now known as the Royal Watercolour Society), and the New Water Colour Society (1832). This palette can mix all possible hues, though the purple, orange and green mixtures are characteristically rather dull or dark, and most color mixtures require use of all three paints.

There are many techniques to produce an acceptable wash, but the student method is to tilt the paper surface (usually after fixing it to a rigid flat support) so that the top of the wash area is higher than the bottom, then to apply the paint in a series of even, horizontal brush strokes in a downward sequence, each stroke just overlapping the stroke above to pull downward the excess paint or water (the bead ), and finally wicking up the excess paint from the last stroke using a paper towel or the tip of a moist brush. Among the best of these are Cheap Joe s, Daniel Smith, Dick Blick and Utrecht. Watercolor pencil is another important tool in watercolors techniques.

This produces an airy, translucent color effect unique to watercolors, especially when a granulating or flocculating pigment (such as viridian or ultramarine blue) is used. In watercolors, a wash is the application of diluted paint in a manner that disguises or effaces individual brush strokes to produce a unified area of color.

Overbrushing and color soaking are the most common flaws of novice watercolor paintings. Palette is also the term for a specific selection of paints (or colors ). The most common sources of paper cellulose are cotton, linen, or alpha cellulose extracted from wood pulp.

Raw (undiluted) paint is picked up with a premoistened, small brush (usually a #4 or smaller), then applied to the paper with small hatching or crisscrossing brushstrokes. The most common failings of natural hair brushes are that the tuft sheds hairs (although a little shedding is acceptable in a new brush), the ferrule becomes loosened, or the wood handle shrinks, warps, cracks or flakes off its lacquer coating. Every watercolor painter works in specific genres and has a personal painting style and tool discipline , and these largely determine his or her preference for brushes.

Note that Leonardo, in his notebooks, cited red, yellow, green and blue (along with white and black) as the painter s primaries , though he may not have had a specific palette in mind; but replacing the cyan paint with a deep blue paint (such as ultramarine blue), and adding a green paint, greatly improves the saturation of both purple and green mixtures in a compact four paint selection, and allows a dark neutral or black to be mixed directly, using only red and green. In the 19th century a six paint split primary palette was introduced and is still advocated today as a solution to the mixing limitations of the three paint primary palette. Among the many significant watercolor artists of this period were Thomas Gainsborough, John Robert Cozens, Francis Towne, Michelangelo Rooker, William Pars, Thomas Hearne and John Warwick Smith.

These stimulated the demand for topographical painters who churned out memento paintings of famous sites (and sights) along the Grand Tour to Italy that was traveled by every fashionable young man or woman of the time. Tube paints left to dry in paint wells are used in exactly the same way as pan paints—the painter simply drips or sprays water over the paint a few minutes before starting work.

Resist painting can also be an affective technique for beginning watercolor artists. This new area of water pulls the wet paint outward in a diffusion fan that is controlled by judging the wetness of the paint and the amount of water applied; if excessive water is used, this brushing produces both an outward diffusion and a backrun into the drying paint.

Washes can be graded or graduated by adding more prediluted paint or water to the mixture used in successive brush strokes, which darkens or lightens the wash from start to finish. To preserve these white areas, many painters use a variety of resists, including masking tape, clear wax or a liquid latex, that are applied to the paper to protect it from paint, then pulled away to reveal the white paper.

These in turn stimulated a greater use of color throughout all painting media, but in English watercolors particularly by the Pre-Raphaelite painters. Watercolor painting also became popular in the United States during middle 19th century; the American Society of Painters in Watercolor (now the American Watercolor Society) was founded in 1866. With tube paints, the excess paint remaining in the palette paint wells should be cleaned out only if the paint has become dirtied with another paint; otherwise the paints should be allowed to dry out promptly and completely, as this prevents mold from forming.

(As paper dries it shrinks, producing a high tension across the paper surface; when painted on, this tension takes up the expansion produced by the paper cockling, so that the paper remains flat.) When the painting was finished, the gummed or glued edge of the paper, including the deckle (which was considered unsightly) was trimmed away. Among the most common and characteristic: Watercolor painters also learn to apply paint to paper and then, when the paint has dried to the right point, brush along the edge of the paint with a flat, mop or sky brush charged with a moderate amount of clear water.

Then the brush is rinsed before picking up any other paint.
