“Color Chart No.139 1” is an abstract artwork created by Gerhard Richter in 1966. It belongs to the art movements of Conceptual Art and Op Art. The artwork is composed of a grid-like arrangement of colored squares, each differing in hue and shade.
The artwork features a systematic layout of nine squares arranged in a three-by-three format. Each square is a solid block of color, presenting a varied palette ranging from pastel pink and cobalt blue to deep red and rich brown. These squares are seemingly chosen and placed without an apparent pattern, emphasizing the conceptual nature of the piece. The artwork engages viewers in an exploration of colors and their interactions within a structured framework.
