Gustave Jacquet sits in the centre of the value range, lending the palette a sense of even, sustained light. Gustave Jacquet builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #852835, registers at 3.7% - sparse enough to feel like a deliberate surprise. Value range is moderate at 50 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Gustave Jacquet's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
