"Sun Coast" is a color lithograph triptych by Richard Anuszkiewicz, the prominent Op Art pioneer known for his investigations of color interaction and optical vibration. Created on three separate sheets of Arches Buff paper with full margins, the work exemplifies Anuszkiewicz's characteristic use of luminous hues and geometric forms to create dynamic visual effects that engage the viewer's perception. The triptych format allows the artist to extend his exploration of chromatic relationships across multiple panels, inviting contemplation of how color and form activate space.
