Émile Bayard is high-key - luminous, open, and weighted toward light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The dominant colour, #E2DFD3, takes 45.3% of the total area, establishing the overall mood before any other hue is introduced. The saturated accent, #B77974, registers at 2.1% - sparse enough to feel like a deliberate surprise. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 4 of Émile Bayard's sequence - a single chapter in a chromatic story told across many works.
