Sepulchral Hampton

#183a16
Notes

Sepulchral Hampton (#183A16) is a deep green 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 (117°, 45%, 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 violet. 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.

Hampton
noun

The English Tudor palace at Hampton Court — and the saturated green of its famous Hampton Court Maze, the oldest surviving hedge maze in the world (planted 1690). Hampton refers to a yew-hedge in the Hampton Court Maze: a deep, slightly cool dark green with the matte finish of densely clipped yew.
