"Sable XX" is an acrylic work on paper by Anne Truitt, the American artist known for her minimalist sculptures and paintings that explore color relationships and spatial perception. The title references sable, a dark brown color, which likely plays a central role in the composition's palette and visual effect. Like much of Truitt's work, this piece demonstrates her systematic approach to abstraction through careful consideration of hue, value, and the materiality of paint on paper.
