Josef Albers's Interaction of Coloris a masterwork in art education. Conceived as a handbook and teaching aid for artists, instructors, and students, this influential book presents Albers's singular explanation of complex color theory principles. Originally published by Yale University Press in 1963 as a limited silkscreen edition with 150 color plates, Interaction of Colorfirst appeared in paperback in 1971, featuring ten color studies chosen by Albers, and has remained in print ever since. With over a quarter of a million copies sold in its various editions since 1963, Interaction of Colorremains an essential resource on color, as pioneering today as when Albers first created it. Fifty years after Interaction's initial publication, this new edition presents a significantly expanded selection of close to sixty color studies alongside Albers's original text, demonstrating such principles as color relativity, intensity, and temperature; vibrating and vanishing boundaries; and the illusion of transparency and reversed grounds. A celebration of the longevity and unique authority of Albers's contribution, this landmark edition will find new audiences in studios and classrooms around the world.
