J.M.W. Turner is high in key: pale, luminous, and filled with optical air. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #53372F functions as the palette's exclamation mark: highest chroma, lowest percentage (3.5%). The palette spans 51 value units: a measured range that delivers coherence over drama. Palette 3 sits within the larger chromatic argument that J.M.W. Turner's complete body of work advances.
