Jean-Baptiste Carpeaux occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #AE7137, registers at 3.6% - sparse enough to feel like a deliberate surprise. Spanning 54 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. In the context of Jean-Baptiste Carpeaux's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
