The value structure of Marcel Duchamp is mid-key: quiet, controlled, and cohesive. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 10.2% is devoted to #CAA872, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 59 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Marcel Duchamp's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
