The use of gouache is not restricted to the basic opaque painting techniques using a brush and watercolor paper. Using gouache as " poster paint" is desirable for its speed as the paint layer dries completely by the relatively quick evaporation of the water. Most 20th-century animations used it to create an opaque color on a cel with watercolor paint used for the backgrounds. Gouache is today much used by commercial artists for works such as posters, illustrations, comics, and for other design work. " En plein air" paintings take advantage of this, as do the works of J. Its quick coverage and total hiding power mean that gouache lends itself to more direct painting techniques than watercolor. Gouache generally dries to a 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. This makes gouache heavier and more opaque than watercolor, and endows it with greater reflective qualities. 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. 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. in tubes, the dextrin has usually been mixed with an equal volume of water. Just as in watercolor, the binding agent has traditionally been gum arabic but since the late nineteenth century cheaper varieties use yellow dextrin. Gouache paint is similar to watercolor, but is modified to make it opaque. Many manufacturers of watercolor paints also produce gouache, and the two can easily be used together. ![]() It is similar to acrylic or oil paints in that it is normally used in an opaque painting style and it can form a superficial layer. 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 used most consistently by commercial artists for posters, illustrations, comics, and other design work. Gouache has a considerable history, having been used for at least twelve centuries. ![]() Gouache ( / ɡ u ˈ ɑː ʃ, ɡ w ɑː ʃ/ French: ), body color, or opaque watercolor is a water-medium paint consisting of natural pigment, water, a binding agent (usually gum arabic or dextrin), and sometimes additional inert material.
