Gouache is pronounced “gwash.” It rhymes with “squash” and it’s simply another type of watercolor paint, with some unusual properties. It does not become absorbed into paper in the same way watercolor and other paints do. It remains on the paper’s surface, in a thick and opaque layer. Gouache is a French word that originates from the Italian “guazzo,” which literally means “water color.” It was first used in medieval illuminated manuscripts and gained popularity among French and Italian painters in 18th century. It was most often used in creating decorative art or landscapes.
