Post-Impressionism sits in the centre of the value range, lending the palette a sense of even, sustained light. The palette tilts toward cool - blues and silver-greys carry the structural weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #825143 delivers the chromatic peak at only 5.5% - a small shot of colour with outsized visual impact. The value range of 53 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.
