The high-key values of Post-Impressionism give it an effulgent, almost bleached quality. The palette tilts toward cool - blues and silver-greys carry the structural weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #9B5E43, registers at 3.9% - sparse enough to feel like a deliberate surprise. The value range of 46 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
