Gouache (; ), body color, or opaque watercolor is a water-medium paint consisting of Pigment, natural pigment, water, a binding agent (usually gum arabic or dextrin), and sometimes additional Chemically inert, inert material. Gouache is designed to be Opacity (optics), opaque. Gouache has a considerable history, having been used for at least twelve centuries. It is used most consistently by Commercial art, commercial artists for posters, illustrations, comics, and other design work.
Gouache is similar to watercolor in that it can be re-wetted and dried to a matte finish, and the paint can become infused into its paper support. It is similar to Acrylic paint, acrylic or oil paints in that it is normally used in an opaque painting style and it can form a superficial layer. Many manufacturers of watercolor paints also produce gouache, and the two can easily be used together.
A form of gouache, with honey or tragacanth gum as binder, is used in Ancient Egyptian art, Ancient Egyptian painting. It is also used in European illuminated manuscripts, as well as Persian miniatures. Although they are often described as "watercolor", Persian miniatures and Mughal miniatures are predominantly examples of gouache. The term gouache, derived from the Italian ''guazzo'', also refers to paintings using this opaque method. "Guazzo", Italian for "mud", was originally a term applied to the early 16th-century practice of applying oil paint over a tempera base,Mayer, Ralph. ''The Artist's Handbook of Materials and Techniques'', Viking Adult; 5th revised and updated edition, 1991. which could give a matted effect. In the 18th century in France, the term ''gouache'' was applied to opaque watermedia.
During the eighteenth century gouache was often used in a mixed technique, for adding fine details in pastel paintings. Gouache was typically made by mixing watercolours based on gum arabic with an opaque white pigment. In the nineteenth century, watercolours began to be industrially produced in tubes and a "Chinese white" tube was added to boxes for this purpose. Gouache tends to be used in conjunction with watercolor, and often ink or pencil, in 19th-century paintings.
Later that century, for decorative uses "poster paint" (as it is known in the U.S.), was mass-produced, based on the much cheaper dextrin binder. It was sold in cans or as a powder to be mixed with water. The dextrin replaced older paint types based on hide glue or Sizing, size. During the twentieth century, gouache began to be specially manufactured in tubes for more refined artistic purposes. Initially, gum arabic was used as a binder but soon cheaper brands were based on dextrin, as is most paint for children.

Description
Gouache paint is similar to watercolor, but is modified to make it Opacity (optics), opaque. Just as in watercolor, the binding agent has traditionally been gum arabic but since the late nineteenth century cheaper varieties use dextrin, yellow dextrin. When the paint is sold as a paste, e.g. in tubes, the dextrin has usually been mixed with an equal volume of water. To improve the adhesive and hygroscopic qualities of the paint, as well as the flexibility of the rather brittle paint layer after drying, propylene glycol is often added. Gouache differs from watercolor in that the particles are typically larger, the ratio of pigment to binder is much higher, and an additional white filler such as chalk - a "body" - may be part of the paint. This makes gouache heavier and more opaque than watercolor, and endows it with greater reflective qualities. Gouache generally dries to a Lightness, value that differs from the one it has when wet (lighter tones generally dry darker and darker tones tend to dry lighter), which can make it difficult to match colors over multiple painting sessions. Its quick coverage and total hiding power mean that gouache lends itself to more direct painting techniques than watercolor. "En plein air" paintings take advantage of this, as do the works of J. M. W. Turner. Gouache is today much used by commercial artists for works such as posters, illustrations, comics, and for other design work. Most 20th-century animations used it to create an opaque color on a cel with watercolor paint used for the backgrounds. Using gouache as "poster paint" is desirable for its speed as the paint layer dries completely by the relatively quick evaporation of the water. The use of gouache is not restricted to the basic opaque painting techniques using a brush and watercolor paper. It is often applied with an airbrush. As with all types of paint, gouache has been used on unusual surfaces from Braille paper to cardboard. A variation of traditional application is the method used in the ''gouaches decoupage, découpées'' (cut collages) created by Henri Matisse. His ''Blue Nude II, Blue Nudes'' series is a good example of the technique. A new variation in the formula of the paint is ''acrylic gouache''.History

Acrylic gouache
A relatively new variation in the formula of the paint is ''acrylic gouache''. Its highly concentrated pigment is similar to traditional gouache, but it is mixed with an acrylic-based binder, unlike traditional gouache, which is mixed with gum arabic. It is water-soluble when wet and dries to a matte, opaque, and water-resistant surface when dry. Acrylic gouache differs from acrylic paint because it contains additives to ensure the matte finish.See also
