Charles D'Oyly distributes its values across the middle register, creating harmony without high contrast. 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. #857B4F delivers the chromatic peak at only 8.2% - a small shot of colour with outsized visual impact. The palette spans 54 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 Charles D'Oyly's complete body of work advances.
