The value structure of Prosper Baccuet is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #E0E2CB, is reserved to 6.4% of the surface, where it acts as a focal punctuation. A value spread of 75 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Prosper Baccuet's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
