A heterogeneous pair of Homage to the Squares reveals the constant change of the painter’s palette. At left we see a cool and stern appearance; at right, a warm and ripening behavior — both may be considered as two new climates.

This interaction of colors exists in all color combinations to a larger or smaller degree, but is in most cases unrecognized even to the trained eye. Interaction permits the knowing colorist to make opaque colors look transparent, heavy ones turn light, colorless neutrals become colorful, warm ones seem cool, and vice versa. It becomes possible to make equal colors look different and different ones look alike, and even defined shapes as well as color areas vanish from our sight.

Although there are other factors which change the psychic effect of colors, such as placement and shape, quantity and recurrence, in my paintings Homage to the Square the interaction of color caused by juxtaposition is one of my main concerns. (From an early commentary for a slide lecture.)
