Philippe de Champaigne 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. Philippe de Champaigne gives 29.2% of the composition to a single #201F18 - a decisive chromatic anchor. Only 12.8% is devoted to #8D8045, yet that small allocation delivers the palette's entire chromatic tension. The palette spans 53 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 3 sits within the larger chromatic argument that Philippe de Champaigne's complete body of work advances.
