Vaulted Colchicum
Vaulted Colchicum (#2D0024) is a deep magenta 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 (312°, 100%, 9%) 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
Old French voulte, vault via Latin volūta (rolled) — past-participle of vault. As a color modifier, vaulted implies the deep-and-architectural-and-Gothic quality of Salisbury-Cathedral-and-Chartres-Cathedral nave-vault overhead-stone-arched ceiling. Sits at the deep-and-architectural end of the grid, parallel to cavernous with cathedral-vault register.
Autumn crocus (Colchicum autumnale) — a Colchicaceae bulb native to Colchis (modern Georgia) whose deep-violet six-tepalled corolla emerges leafless in late autumn, named for the home of Medea. Colchicum color refers to a fully opened Colchicum autumnale corolla on a Cotswold meadow: a saturated, slightly cool deep violet with the velvet finish of fresh six-tepalled chalice-corolla. The plant is the source of colchicine, used to treat gout.
