Jean Delville keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #B68387, registers at 4.7% - sparse enough to feel like a deliberate surprise. The palette spans 50 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 Jean Delville's complete body of work advances.
