Gouache is a resoluble, quick-drying, water-based colour of excellent opacity with a consistent, velvety finish. Made in the classic tradition, all colours are carefully triple-milled to ensure maximum brilliance and even coating of pigments. This method has been proven by the test of time. Concentrated pigment colour ensures a little goes a long way. Genuine, water-based gouache in various forms has been in use since ancient times. The 14th century saw its use in beautifully illustrated manuscripts and JMW Turner, the English watercolourist, used gouache extensively on coloured papers.
