Mid-key values give history painting its characteristic quietness - nothing blazes, nothing disappears. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #8A7350 delivers the chromatic peak at only 11.3% - a small shot of colour with outsized visual impact. The full value range is 55 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
