Low-key values are the structural spine of Marie-Guillemine Benoist, giving it gravity and atmosphere. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. A single dominant - #2B2317 at 34.9% - sets the character of the whole composition. The saturated accent, #865E3C, registers at 4.3% - sparse enough to feel like a deliberate surprise. A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. This is palette 6 of Marie-Guillemine Benoist's sequence - a single chapter in a chromatic story told across many works.
