Wyndham Lewis sits in the centre of the value range, lending the palette a sense of even, sustained light. Wyndham Lewis builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #9A7C61 delivers the chromatic peak at only 3.7% - a small shot of colour with outsized visual impact. The palette spans 48 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 Wyndham Lewis's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
