Piero della Francesca is high-key - luminous, open, and weighted toward light. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #AA8759, registers at 12.7% - sparse enough to feel like a deliberate surprise. The value range spans 75 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Palette 1 sits within the larger chromatic argument that Piero della Francesca's complete body of work advances.
