Roberta Smith wrote in Donald Judd’s 1975 catalogue raisonné that Judd was “concerned with the development of non-relational composition based on equal, repeating parts,” adding that this painting “seems to indicate in advance an approach to materials which Judd succeeds with best in three dimensions: his involvement with them is based on what they do naturally, on their inherent qualities. . . . Each area is given equal emphasis; each has its own colour and surface that indicate a different decision. . . . The areas exist equally in a series of intervals, spatially even.”¹
