Mid-key values give Paul Cezanne its characteristic quietness - nothing blazes, nothing disappears. Paul Cezanne 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. The dominant colour, #3F3C39, takes 28.2% of the total area, establishing the overall mood before any other hue is introduced. Only 3.0% is devoted to #D0B56C, yet that small allocation delivers the palette's entire chromatic tension. The palette spans 47 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. Palette 4 sits within the larger chromatic argument that Paul Cezanne's complete body of work advances.
