John Peter Russell is high in key: pale, luminous, and filled with optical air. John Peter Russell builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 3.7% is devoted to #A98D5F, yet that small allocation delivers the palette's entire chromatic tension. Value range is moderate at 31 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that John Peter Russell's complete body of work advances.
