This book is revolutionary in that it explains color and composition in an entirely new way. As far as I know it is the first of its kind in human history.
Instead of relying on the commonly used color wheel, divided into 12 colors, it explains how every perceivable color relates to each other in a mathematically definable way.
Composition is explained systematically based on "unity within diversity" and balances, areas and colors that relate to each other, with texture.
Art can be either designed or corrected with this system.
