The value structure of William Hamilton is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 8.7% is devoted to #B0904D, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 60 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 4 of William Hamilton's sequence - a single chapter in a chromatic story told across many works.
