Paolo Uccello is high-key - luminous, open, and weighted toward light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The most saturated colour, #C78437, is reserved to 7.6% of the surface, where it acts as a focal punctuation. The palette spans 49 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Paolo Uccello's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
