The value structure of Claude Lorrain is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The dominant colour, #2A261E, takes 25.2% of the total area, establishing the overall mood before any other hue is introduced. The most saturated colour, #BE8C5E, is reserved to 2.6% of the surface, where it acts as a focal punctuation. The full value range is 63 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Claude Lorrain's full range of palettes, group 10 represents one movement in an ongoing chromatic dialogue.
