John Boultbee distributes its values across the middle register, creating harmony without high contrast. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. At 6.7%, #6F3417 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. The palette is a signature: John Boultbee's particular sense of value, warmth, and colour weight made legible.
