Paul Signac is strongly light-biased - shadow is suggested rather than declared. 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 saturated accent, #BA5118, registers at 2.8% - sparse enough to feel like a deliberate surprise. The full value range is 57 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. The palette is a signature: Paul Signac's particular sense of value, warmth, and colour weight made legible.
