The value structure of Cubism is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #AD9665 delivers the chromatic peak at only 3.2% - a small shot of colour with outsized visual impact. The palette spans 46 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
