Sepulchral Sidon

#390f45
Notes

Sepulchral Sidon (#390F45) 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 (287°, 64%, 16%) 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 green. 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.

Sidon
noun

Ancient Phoenician city on the Lebanese coast — co-eval with Tyre in Tyrian purple production, and the slightly older of the two purple-dye centers. Sidon color refers to a Sidon-produced Tyrian purple-dyed Phoenician trade textile: a saturated, slightly cool deep violet with the matte finish of multi-bath Hexaplex trunculus shellfish dye on hand-loomed Levantine cloth.
