Philippe de Champaigne keeps values measured and balanced, a hallmark of tonal restraint. Philippe de Champaigne builds on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. Only 4.0% is devoted to #83542D, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 4 of Philippe de Champaigne's sequence - a single chapter in a chromatic story told across many works.
