Post-Impressionism distributes its values across the middle register, creating harmony without high contrast. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #92634A functions as the palette's exclamation mark: highest chroma, lowest percentage (4.9%). The palette spans 37 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
