The value structure of Louis Léopold Robert is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #C29C48, is reserved to 3.3% of the surface, where it acts as a focal punctuation. The full value range is 64 units: broad enough to build convincing three-dimensional form. The palette is recognisably Louis Léopold Robert's own: particular in its temperature, chroma, and the economy of its brightest note.
