Mid-key values give Cloisonnism its characteristic quietness - nothing blazes, nothing disappears. 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. The saturated accent, #AD4B35, registers at 2.6% - sparse enough to feel like a deliberate surprise. Value range is moderate at 54 units - enough contrast for legibility, not so much as to fragment the tonal unity.
