Sepulchral Hiwa

#2a2e04
Notes

Sepulchral Hiwa (#2A2E04) is a deep yellow 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 (66°, 84%, 10%) 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 blue. 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.

Hiwa
noun

The Japanese name for the Eurasian siskinSpinus spinus — and for the bright yellow-green of its plumage. Hiwa-iro refers to the saturated yellow-green color used in kosode kimono linings and woodblock prints. The color refers to a freshly molted siskin: a saturated, slightly green-shifted yellow with the matte finish of carotenoid feathers.
