The high-key values of Academicism give it an effulgent, almost bleached quality. 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. #DED4BE delivers the chromatic peak at only 10.0% - a small shot of colour with outsized visual impact. A value spread of 68 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
