Charles Dixon is high in key: pale, luminous, and filled with optical air. Charles Dixon tilts toward cool - blues and silver-greys carry the structural weight. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #68ABD6, covers 25.6% of the surface: too much to call an accent, too strong to ignore. A value spread of 59 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. This is the light Charles Dixon preferred, made measurable.
