Untitled is a telling example of Karl Benjamin’s color investigations of the 1950s, which came to indentify him as a hard-edged abstract painter. Benjamin often employed color to determine geometric form, making color the subject of his paintings. In Untitled (1958), vibrant pinks, reds, and purples define jagged shapes across the canvas. Creating a flat picture plane with no sense of depth, Benjamin eliminates any sign of the artist’s hand by using broad brush strokes.
