The value structure of Jean-Joseph-Xavier Bidauld is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #75723D - appears at just 2.5%, deployed as a precision accent against the quieter ground. A value spread of 63 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 7 sits within the larger chromatic argument that Jean-Joseph-Xavier Bidauld's complete body of work advances.
