Arthur Segal sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #D4CBB5 claims 25.6% of the surface, functioning as the work's tonal foundation. The saturated accent, #A98F4E, registers at 9.8% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 59 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode Arthur Segal's instinctive sense of how much of each quality the eye can hold.
