Ambrogio Lorenzetti sits in the centre of the value range, lending the palette a sense of even, sustained light. Ambrogio Lorenzetti 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 chromatic peak belongs to #B59159, and at 19.5% it dominates, not decorates. At 54 units across the value scale, the palette keeps contrast readable without letting it dominate. This is palette 6 of Ambrogio Lorenzetti's sequence - a single chapter in a chromatic story told across many works.
