The value structure of Ippolito Caffi is mid-key: quiet, controlled, and cohesive. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #9E7A51, registers at 10.4% - sparse enough to feel like a deliberate surprise. 63 units of value range underpin the palette's structural clarity: the eye always knows where light falls. In the context of Ippolito Caffi's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
