The value structure of Pierre-Auguste Cot is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #470E1C, registers at 7.8% - sparse enough to feel like a deliberate surprise. The full value range is 67 units: broad enough to build convincing three-dimensional form. Taken together, these qualities constitute Pierre-Auguste Cot's chromatic voice - distinctive enough to be read across an entire body of work.
