nude painting (nu) distributes its values across the middle register, creating harmony without high contrast. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #A87A56 delivers the chromatic peak at only 6.4% - a small shot of colour with outsized visual impact. Value range is moderate at 46 units - enough contrast for legibility, not so much as to fragment the tonal unity.
