The value structure of Henri Rousseau is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. A single dominant - #3B3E2B at 25.1% - sets the character of the whole composition. Only 4.0% is devoted to #8B963B, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 60 units: broad enough to build convincing three-dimensional form. 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 Henri Rousseau's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
