Values in Mannerism tilt decisively toward white, giving the palette its luminous character. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #3E2B1C, registers at 5.2% - sparse enough to feel like a deliberate surprise. The full value range is 74 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
