Sepulchral Jambū

#4b1a6f
Notes

Sepulchral Jambū (#4B1A6F) is a deep indigo 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 (275°, 62%, 27%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary lime. 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.

Jambū
noun

Sanskrit जम्बू, the rose-apple (Syzygium jambos) — the eponymous fruit of Jambūdvīpa, the Continent of the Jambu Tree in Hindu and Buddhist cosmology, and a stock floral motif in Sanskrit poetry. Jambū color refers to a freshly cut Syzygium jambos drupe: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich fruit-flesh on the cut surface.
