A masterful example of Josef Albers' lifelong exploration of color interaction and geometric abstraction, *DR-a* presents precisely rendered squares or rectangles in carefully chosen hues that challenge the viewer's perception of depth and spatial relationships. Executed as a screenprint in colors on heavy wove paper, the work reflects Albers' belief that color is never absolute, but constantly influenced by its surrounding tones and context. The full margins frame the composition with quiet authority, allowing the interplay of color and form to resonate with characteristic intellectual rigor and visual clarity.
