The high-key values of portrait give it an effulgent, almost bleached quality. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #77513B - appears at just 4.2%, deployed as a precision accent against the quieter ground. The full value range is 63 units: broad enough to build convincing three-dimensional form.
