Values in John Augustus Atkinson tilt decisively toward white, giving the palette its luminous character. 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. #D6BE8B is not a small accent - at 24.3% it qualifies as a major presence and gives the palette its chromatic identity. The full value range is 55 units: broad enough to build convincing three-dimensional form. 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 1 of John Augustus Atkinson's sequence - a single chapter in a chromatic story told across many works.
