Henri Rousseau is strongly light-biased - shadow is suggested rather than declared. Henri Rousseau builds on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. #B4AB88 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.4%). The value range spans 66 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. 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 palette 1 of Henri Rousseau's sequence - a single chapter in a chromatic story told across many works.
