Ippolito Caffi is high in key: pale, luminous, and filled with optical air. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Mid-saturation across the board: the palette has colour character without chromatic excess. #94BBED functions as the palette's exclamation mark: highest chroma, lowest percentage (8.8%). 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. In the context of Ippolito Caffi's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
