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. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #202B30 functions as the palette's exclamation mark: highest chroma, lowest percentage (11.7%). 46 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 15 sits within the larger chromatic argument that Paul Cezanne's complete body of work advances.
