Robert Campin sits in the centre of the value range, lending the palette a sense of even, sustained light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #D08A79, registers at 6.1% - sparse enough to feel like a deliberate surprise. A value spread of 59 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 6 sits within the larger chromatic argument that Robert Campin's complete body of work advances.
