The value structure of Concretism is mid-key: quiet, controlled, and cohesive. Temperature reads distinctly warm: the reds and earth tones carry the compositional weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. A single dominant - #916650 at 32.5% - sets the character of the whole composition. #D95E10 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.9%). A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light.
