Mid-key values give history painting its characteristic quietness - nothing blazes, nothing disappears. 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. #D6BD43 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.8%). The palette spans 51 value units: a measured range that delivers coherence over drama. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
