Since the beginning of his career, Ellsworth Kelly's emphasis on pure form and color and his impulse to suppress gesture in favor of creating spatial unity have played a pivotal role in the development of abstract art in America. A major influence on Pop Art, Minimalism, hard-edge and color field painting, Ellsworth Kellyââ¬â¢s best-known works are distinguished by sharply delineated shapes flatly painted in vivid color, such as Colors for a Large Wall (1951). His abstract paintings are inspired by the interplay of light, space, and color in the architecture around him. In contrast, Kellyââ¬â¢s automatic drawings feature delicate outlines of bodies and flora.
