cityscape is high in key: pale, luminous, and filled with optical air. 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, #B89B75, registers at 6.0% - sparse enough to feel like a deliberate surprise. The full value range is 58 units: broad enough to build convincing three-dimensional form.
