Colour Mixing Guide: Watercolour [PDF ebook] 

A clear, comprehensive guide to colour mixing for the watercolour artist. It begins with simple colour theory and a colour wheel, with a template provided so that readers can paint their own; a vital step towards understanding colour. There is vividly illustrated guidance on complementary, warm and cool colours, colour tone, using a limited palette, dull and bright colours and factoring in local colour. There follows an array of essential colour mixes using widely available Winsor & Newton colours. A beautifully presented and practical guide to understanding and mixing colours. Watercolour artists from beginners to more experienced painters will find this a handy, comprehensive guide.
