Nathan Altman distributes its values across the middle register, creating harmony without high contrast. 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. The saturated accent, #C2B988, registers at 5.1% - sparse enough to feel like a deliberate surprise. A value spread of 57 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. In the context of Nathan Altman's full range of palettes, group 7 represents one movement in an ongoing chromatic dialogue.
