Sepulchral Wisteria

#28256d
Notes

Sepulchral Wisteria (#28256D) 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 (243°, 49%, 29%) 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.

Wisteria
noun

The genus Wisteria, the climbing legume vines of East Asia — W. sinensis (Chinese) and W. floribunda (Japanese) — whose pendulous racemes of pale blue-violet flowers drape ten meters of pergola in late spring. The color refers to a fresh wisteria flower cluster: a soft, slightly violet-shifted pale blue with the matte finish of pea-family florets. Lighter than lilac, cooler than periwinkle, with the architectural weight of a vine that ages into structure.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
