Sooty Crozier

#400747
Notes

Sooty Crozier (#400747) is a deep violet with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (293°, 82%, 15%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sooty
adjective

Old English sōt, soot — adjectival suffix -y. As a color modifier, sooty implies the deep-matte-black quality of multi-decade chimney-and-furnace soot-and-creosote-residue surfaces, the Brontë-period Yorkshire-cottage hearth-and-flue patina. Sits at the deep-and-warm end of the grid, parallel to smoky and pitchy.

Crozier
noun

Old French crochier, crooked staff — the bishop's pastoral staff, with its top crook often cast or carved in deep-violet enamel-and-gilt to symbolize episcopal authority. Crozier color refers to a 14th-century Limoges-school enameled crozier-crook: a saturated, slightly cool deep violet with the glossy finish of plique-à-jour enamel over gilt copper. The crook shape echoes the ancient lituus augur staff.
