The value structure of Karl Joseph Kuwasseg is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 4.0%, #9E6D2F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 60 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. This is the light Karl Joseph Kuwasseg preferred, made measurable.
