The Elements of Color

Itten begins with the basics of colour physics and the difference between colour as a material and colour as a perception. He then introduces his twelve-part colour circle and explains how harmonious combinations can be built from it. The heart of the book is his account of seven contrasts: of hue, of light and dark, of cold and warm, of complements, simultaneous contrast, contrast of saturation and contrast of extension, or proportion.

Each contrast is explained in a few pages and illustrated with simple colour plates, often squares within squares, that show the effect clearly. Itten also discusses colour mixing, the expressive qualities of colours and the idea that each person has a personal colour palette. Some of his ideas are more poetic than scientific and are still debated, but the core lessons remain widely taught in art schools.

Short enough to read in an afternoon and rich enough to study for years. It pairs well with Albers's Interaction of Color. Keep a set of paints or coloured paper nearby; the exercises are far more convincing when you try them yourself. About 96 pages in the Wiley hardcover.
