Joseph Duplessis occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #C2AC9B, is reserved to 9.9% 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 has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 3 of Joseph Duplessis's sequence - a single chapter in a chromatic story told across many works.
