The colour logic of Cubism is concentrated here: its characteristic value range, temperature bias, and chroma level. Cubism distributes its values across the middle register, creating harmony without high contrast. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #704730 - appears at just 7.6%, deployed as a precision accent against the quieter ground. 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. The Cubism movement spoke in this palette's vocabulary.
