Sepulchral Yorkshire

#21301a
Notes

Sepulchral Yorkshire (#21301A) 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 (101°, 30%, 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 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.

Yorkshire
noun

The English northern county — and the muted green of Yorkshire moors, sheep pastures, and the rolling Yorkshire Dales. Yorkshire color refers to a Dales sheep pasture in May: a soft, slightly muted yellow-green with the matte finish of close-cropped Calluna-and-grass moor.
