The value structure of cityscape is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #755048, registers at 5.0% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 58 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
