Constantin Guys occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #5E442F, registers at 11.7% - sparse enough to feel like a deliberate surprise. The full value range is 65 units: broad enough to build convincing three-dimensional form. The palette is recognisably Constantin Guys's own: particular in its temperature, chroma, and the economy of its brightest note.
