Cubism is high-key - luminous, open, and weighted toward light. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #94774D - appears at just 7.5%, deployed as a precision accent against the quieter ground. A value spread of 66 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light.
