Some words about gouache

Gouache (from the Italian guazzo, "water paint") or bodycolor (the term preferred by art historians) is a type of paint consisting of pigment suspen- ded in water. Gouache differs from watercolor in that the particles are larger, the ratio of pigment to water is much higher, and an additional, inert, white pigment such as chalk is also present. This makes gouache heavier and more opaque, with greater reflective qualities. The term was applied to the watermedia in the 18th century in France, although the technique is considerably older. Lighter tones generally dry darker, while darker tones tend to dry lighter, This, combined with its quick cover- age and total hiding power, mean that gouache lends itself to more immediate techniques than water- colour. It is used more consistently for graphic works such as posters, illustra- tions, comics, and for other design work
