Henri Rousseau keeps values measured and balanced, a hallmark of tonal restraint. 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. 27.4% of the palette belongs to #5B605F, a concentration that makes it the unmistakable visual centre. The saturated accent, #A07744, registers at 4.6% - sparse enough to feel like a deliberate surprise. Value range is moderate at 48 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 9 of Henri Rousseau's sequence - a single chapter in a chromatic story told across many works.
