The value structure of Mannerism is mid-key: quiet, controlled, and cohesive. Warmth dominates - the palette leans heavily on the yellow-orange-red arc of the colour wheel. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #A74B37, registers at 5.6% - sparse enough to feel like a deliberate surprise. 65 units of value range underpin the palette's structural clarity: the eye always knows where light falls.
