The value structure of Claude Lorrain is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #89A7C1, registers at 7.9% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 74 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Claude Lorrain's full range of palettes, group 9 represents one movement in an ongoing chromatic dialogue.
