Arthur Beecher Carles sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #9C5937, registers at 3.0% - sparse enough to feel like a deliberate surprise. The palette spans 42 value units: a measured range that delivers coherence over drama. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Arthur Beecher Carles's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
