Pierre Daura distributes its values across the middle register, creating harmony without high contrast. 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 most saturated colour, #5D4F33, is reserved to 4.0% of the surface, where it acts as a focal punctuation. At 35 units across the value scale, the palette keeps contrast readable without letting it dominate. 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 the light Pierre Daura preferred, made measurable.
