Josef Albers began the Homage to the Square series in 1950 and continued until his death in 1976. It includes more
than two thousand paintings that explore the interaction between colors and between colors and their environment.
As the artist showed in his lesson on “the magic of color” and then again in his fundamental book Interaction of Color,
a color is never seen as it really is – as it physically is, but always in relation to its environment (appearing
darker on a light background and lighter on a dark background for example).
So the same color can look like two different colors, or to put it another way, one color becomes two.
