The value structure of Cubo-Expressionism is mid-key: quiet, controlled, and cohesive. Warm hues command this palette; it favours the reds, oranges, and yellows of firelight and earth. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #715239 - appears at just 8.1%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 59 units of the value scale - a span that creates natural depth.
