Eduard Boehm keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #AF8C5B functions as the palette's exclamation mark: highest chroma, lowest percentage (5.3%). A value spread of 57 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Eduard Boehm's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
