Erebine Loropetalum

#18163e
Notes

Erebine Loropetalum (#18163E) 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°, 48%, 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Erebine
adjective

Greek Erebine, of Erebus — adjectival form of Erebus, the primordial deity of darkness in Hesiod's Theogony. As a color modifier, erebine implies the deepest primordial-darkness of pre-cosmic chaos, with literary-cosmological register. Sits at the deepest-and-coolest end of the grid, parallel to Stygian and Cimmerian.

Loropetalum
noun

Asian Chinese fringe flower (Loropetalum chinense var. rubrum) — an evergreen shrub native to southern China cultivated worldwide for its strap-like fringed flowers and burgundy foliage. Loropetalum color refers to a L. chinense flush of fringed flowers on burgundy foliage: a saturated, slightly cool deep blue-violet with the velvet finish of dense ribbon-petal flowers. The genus name combines Greek loros (strap) and petalon (petal).
