Sepulchral Caspian

#123322
Notes

Sepulchral Caspian (#123322) is a deep teal 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 (149°, 48%, 14%) 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 magenta. 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.

Caspian
noun

The world's largest inland body of water — between Iran, Russia, Kazakhstan, Turkmenistan, and Azerbaijan. Caspian color refers to mid-depth Caspian Sea water: a saturated, slightly cool deep blue-green with the optical complexity of slightly brackish water over silt-rich bottom.
