Andrea Mantegna dwells firmly in the shadows, with no more than a whisper of light. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #93742D, registers at 7.4% - sparse enough to feel like a deliberate surprise. At 55 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Andrea Mantegna's full range of palettes, group 12 represents one movement in an ongoing chromatic dialogue.
