Amazon.com description: Product Description: Artists working with acrylics, watercolors, and oil paints will want to keep this book handy as a helpful quick-reference guide. It presents detailed color-mixing charts, and because color mixing in each medium produces different results, acrylics, watercolors, and oils are each given their own separate group of charts. Starting with 25 widely used artist's pigments--including Windsor lemon, cobalt blue, cadmium yellow, and others--the charts show gradations of colors and color combinations that produce more than 2,000 hues and shades. The book's spiral binding keeps pages lying flat for easy reference while artists work on their paintings.
