Andrea del Castagno keeps values measured and balanced, a hallmark of tonal restraint. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Mid-saturation across the board: the palette has colour character without chromatic excess. The saturated accent, #F6DC9F, registers at 4.0% - sparse enough to feel like a deliberate surprise. A value spread of 68 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Andrea del Castagno's palette 7 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
