Untitled (from the Portfolio "Ten Works X Ten Painters") 1964

Ad Reinhardt's "Untitled" from 1964, a striking example of abstract Minimalism, is a black square set against a cream-colored background. Reinhardt was known for his exploration of color, or rather, the absence of it. By simplifying his forms to the absolute minimum, he challenged viewers to engage directly with the canvas, forcing them to confront the very nature of art itself. The work is currently on display at the Albright-Knox Art Gallery in Buffalo, New York.
