A masterful example of Josef Albers' lifelong investigation into color interaction, this screenprint presents nested rectangular forms in carefully chosen hues that appear to shift and vibrate against one another. Part of his *Ten Variants* series, the work demonstrates how the same compositional structure can yield entirely different visual sensations depending on the relationships between colors. Printed on Rives BFK paper, the crisp, flat planes of color achieve a precision that reinforces Albers' belief that color perception is fundamentally deceptive and ever-changing.
