Marcel Duchamp distributes its values across the middle register, creating harmony without high contrast. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 7.0% is devoted to #764828, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 61 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette is recognisably Marcel Duchamp's own: particular in its temperature, chroma, and the economy of its brightest note.
