Light floods Post-Impressionism; the palette keeps values pale and airy across its range. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 3.3% is devoted to #916451, yet that small allocation delivers the palette's entire chromatic tension. The value range of 53 units sits in the comfortable middle: enough depth, enough light, neither extreme. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
