Values in Pierre-Henri de Valenciennes rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #C9B796 - appears at just 11.4%, deployed as a precision accent against the quieter ground. A value spread of 55 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. This is palette 4 of Pierre-Henri de Valenciennes's sequence - a single chapter in a chromatic story told across many works.
