Sepulchral Habanero

#4c2004
Notes

Sepulchral Habanero (#4C2004) is a deep orange 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 (23°, 90%, 16%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sepulchral
adjective

Latin sepulcrālis, of the burial-place — adjectival form of sepulcrum. As a color modifier, sepulchral implies the deep funereal-and-formal darkness of Holy-Sepulchre-and-rock-cut royal-tomb interiors of medieval-and-Renaissance Christendom. Sits at the deep-and-funereal end of the grid, parallel to entombed and funereal in tone, both literary and architectural.

Habanero
noun

Capsicum chinense, the small lantern-shaped pepper from the Yucatán — among the hottest peppers in regular culinary use. The color refers to a ripe orange habanero: a saturated, slightly red orange with the satin finish of waxy fruit skin. Warmer than tangerine, brighter than carrot.
