High Renaissance is high in key: pale, luminous, and filled with optical air. Built on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. A single dominant - #D5CDBA at 25.0% - sets the character of the whole composition. At 2.4%, #C25443 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 60 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
