First published in 1963, Interaction of Color was conceived by Josef Albers as a teaching manual for artists, educators, and students. Through experiments and practical examples, the book presents the color theory Albers developed over years of teaching at the Bauhaus. The aim of Albers’ lessons is to train the eye for color—that sensitivity to light and tone that cannot be developed through the theoretical study of optics and color systems alone. The result is a simple yet structured path designed to stimulate the development of a “practical way of thinking,” where experimentation and discovery accompany creativity. Fifty years after its first release, Interaction of Color remains a cornerstone in the study of color. This new edition features an updated and expanded selection of color plates that illustrate the principles Albers expressed in his lessons and demonstrations. Josef Albers (Bottrop, 1888 – New Haven, 1976), German painter and designer, was trained within the Bauhaus environment, where he entered as a student in 1920 and remained as a teacher until its closure in 1933. He then moved to the United States, where he taught for sixteen years at Black Mountain College in North Carolina. In 1950, he was appointed head of the Department of Graphic and Design at Yale University. After retiring in 1958, he was awarded the title of Professor Emeritus. In 1968, Albers was elected a member of the National Institute of Arts and Letters. He was the first living artist to be honored with a retrospective at the Metropolitan Museum of Art in New York, in 1971.
