Sebastiano Conca distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 7.0%, #7C4F33 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 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 Sebastiano Conca's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
