Interaction of Color, a masterwork of one of the most influential artists of the twentieth century, is a brilliant display and explanation of the characteristics of color and the conditions under which certain optical phenomena occur. Originally published in book form, Interaction of Color is now available for the first time in a CD-ROM edition, extending Josef Albers's color teaching into the realm of the computer and revealing a range of miraculous color effects in a new medium, including the way that one color can appear as two and how disparate colors can appear alike in varying settings.
