The palette of Expressionism sits in the lower register of the value scale - dense, contained, and weighted. The palette balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #AA834A - appears at just 4.2%, deployed as a precision accent against the quieter ground. The full value range is 60 units: broad enough to build convincing three-dimensional form. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere.
