Josef Albers, Color Study for White Line Square. "Josef Albers (1888–1976) is best known for his series of paintings, Homage to the Square, in which he endlessly explored color relationships within a similar format of concentric squares. Less well-known are the studies he made for these compositions. With approximately sixty oil sketches on paper, this exhibition will reveal a private side of Albers's work. These sketches were never exhibited in the artist's lifetime and have rarely been seen after his death."
