The value structure of John Collier is mid-key: quiet, controlled, and cohesive. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The most saturated colour, #C9AF68, is reserved to 7.4% of the surface, where it acts as a focal punctuation. A value spread of 68 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. In the context of John Collier's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
