The value structure of Cubism is mid-key: quiet, controlled, and cohesive. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. #E46734 at 33.3% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. #FCEE52 at 1.5% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. At 69 units of value range, the palette has the tonal breadth to sustain complex spatial readings.
