Arthur Segal is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #D5CBBA, covers 9.5% of the surface: too much to call an accent, too strong to ignore. 62 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 2 of Arthur Segal's sequence - a single chapter in a chromatic story told across many works.
