Andrea del Castagno sits in the centre of the value range, lending the palette a sense of even, sustained light. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #E2CCA2, registers at 7.2% - 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. Andrea del Castagno's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
