Duccio keeps values measured and balanced, a hallmark of tonal restraint. 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, #B18668, is reserved to 10.4% of the surface, where it acts as a focal punctuation. Value range is moderate at 39 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Duccio's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
