This book has been a classic color theory reference in Europe for several years, and is available now, for the first time, in English translation. The book is arranged to follow light from a stimulus outside the human body, through the reaction of the visual organs of the body and ultimately to the occurrence of the visual experience in the brain. Colorful schematic drawings and photographs presented with explanatory captions demonstrate many elements of color theory from the organization of color to the perception of a rainbow. Beyond as explanation of the actual processes, Mr Zwimpfer demonstrates the total relationship which takes the perception of color beyond a mere passive registering, such as in photography, to a three-dimensional perception of our world. The book will fascinate and inform artists, photographers, students and others who are interested in color theory.
