Pietro Perugino works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Pietro Perugino orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #BC694C, registers at 5.1% - sparse enough to feel like a deliberate surprise. A value spread of 64 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This is palette 4 of Pietro Perugino's sequence - a single chapter in a chromatic story told across many works.
