Sepulchral Cappadocia

#12153c
Notes

Sepulchral Cappadocia (#12153C) is a deep blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (236°, 54%, 15%) 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 yellow. 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.

Cappadocia
noun

Central Anatolian volcanic-tuff region in Turkey, famous for its Hittite-era nazar (evil-eye) amulets cast in deep-cobalt-blue glass. Cappadocia color refers to a hand-blown Cappadocian nazar glass disc on a Göreme bazaar stall: a saturated, slightly cool deep blue-violet with the glossy finish of cobalt-and-iron-flux Anatolian glassmaking. Distinct from the same region's pale-tuff stone formations.
