Duccio occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Duccio balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #B07954, registers at 7.9% - sparse enough to feel like a deliberate surprise. At 36 units across the value scale, the palette keeps contrast readable without letting it dominate. Duccio's palette 12 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
