Arthur Segal is strongly light-biased - shadow is suggested rather than declared. Arthur Segal tilts toward cool - blues and silver-greys carry the structural weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The chromatic peak belongs to #E4D9C4, and at 24.9% it dominates, not decorates. From deepest dark to palest light, the palette traverses 62 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Arthur Segal's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
