The value structure of John Peter Russell is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #BC996C functions as the palette's exclamation mark: highest chroma, lowest percentage (10.0%). The palette spans 41 value units: a measured range that delivers coherence over drama. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. The palette is recognisably John Peter Russell's own: particular in its temperature, chroma, and the economy of its brightest note.
