The value structure of cityscape is mid-key: quiet, controlled, and cohesive. The palette balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 3.1% is devoted to #91533C, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 64 units of the value scale - a span that creates natural depth.
