Winsor & Newton have been producing fine artist designer gouache since the mid 1930's. Today the Designers Gouache range benefits from significant developments in technology and is smoother, flatter, more opaque and more brilliant than ever before. Designers Gouache colours are a range of opaque watercolours, mainly used by designers, illustrators and commercial artists to create vibrant illustrations in solid colour. Gouache is also widely used in fine art as an opaque watercolour. Can be used thinly for a wash at the start of a painting then applied in thicker layers towards the end. Unlike transparent watercolour, where you need to plan and reserve the white of the paper, gouache is more controllable and enables you to remove mistakes and re-paint. Quick drying paint and superb covering power makes a wash like a watercolour blends like an oil colour brushes like an acrylic. The Introduction Set includes 10x14ml tubes and the Primary Set includes 6x14ml tubes.
