Mid-key values give Paolo Uccello its characteristic quietness - nothing blazes, nothing disappears. Warmth dominates - the palette of Paolo Uccello leans heavily on the yellow-orange-red arc of the colour wheel. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The saturated accent, #B17839, registers at 7.0% - sparse enough to feel like a deliberate surprise. A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 4 sits within the larger chromatic argument that Paolo Uccello's complete body of work advances.
