The value structure of William Orpen is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. At 3.5%, #232C71 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The palette spans 50 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 6 sits within the larger chromatic argument that William Orpen's complete body of work advances.
