Winsor & Newton has been making Designers Gouache since 1935. Ever popular among designers, illustrations and commercial artists, the Winsor & Newton Designers Gouache paint is perfect for creating bold and vibrant artworks. Unlike watercolour, gouache colours are vivid and opaque and provide a solid, smooth finish – colours can be mixed, diluted with water, used straight from the tube or mixed with watercolour for a flat, matte colour effect. 84 colours available. The Winsor & Newton Designers Gouache range consists of colours from Series 1, 2, 3 and 4, varying in pigment rarity. 14ml tubes.
