The value structure of Louis de Caullery is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #CCBF72 - appears at just 8.0%, deployed as a precision accent against the quieter ground. A value spread of 62 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. Louis de Caullery's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
