Values in Arthur Segal rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #232220 claims 28.4% of the surface, functioning as the work's tonal foundation. #674228 delivers the chromatic peak at only 7.8% - a small shot of colour with outsized visual impact. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Arthur Segal's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
