Donald Judd. Untitled. 1979

By 1979, Judd had been refining his approach to minimalism for over a decade. In this piece, Judd used Douglas fir plywood, a simple, natural material, and paired it with the bright, artificial cadmium red light acrylic. This contrast between the organic wood and the bold, synthetic red highlights Judd's interest in how materials and colors interact without referencing anything beyond themselves.
