Richard Anuszkiewicz

Primary Hue creates an optical illusion of nested squares in differing shades of red, yet only a single color underlies the radiating lines. The lines alternate green and blue as they travel from the center to the painting’s edge, causing a seeming transformation in the red background.

Anuszkiewicz is identified with the Op Art movement of the 1960s and 1970s, as was Bridget Riley. That movement emphasized the abstract use of geometric forms to develop dynamic, visually deceptive compositions.
