Diogène Maillart is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 9.0% is devoted to #C59464, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 56 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 3 of Diogène Maillart's sequence - a single chapter in a chromatic story told across many works.
