Like watercolours, gouache is a water-soluble "tempera" paint. The main difference between the two is that gouache is opaque. Its use in schools has often wrongly given it the reputation of a medium reserved for children and students. Famous artists such as Raoul Dufy have shown otherwise. The opacity of gouache has made full use of Pebeo's range of pigment-rich paints. The surface coverage of gouache along with its resistance to light and its velvety matte finish will delight adult artists as well as children.
