Ebon Coquille

#63244a
Notes

Ebon Coquille (#63244A) is a deep magenta 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 (324°, 47%, 26%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ebon
adjective

A poetic shortening of ebony — used principally in nineteenth-century verse and Edgar Allan Poe (The Ravenebon bird). As a color modifier, ebon is a literary register for deep black with slight warmth, distinct from the cooler inky and the harder jet. Carries the same weight as the wood it borrows from.

Coquille
noun

French coquille, shell — particularly the coquille Saint-Jacques (Pecten maximus, scallop shell) whose interior surface displays a deep-magenta-to-pink iridescent nacre. Coquille color refers to a freshly opened Pecten maximus shell-interior in raking light: a saturated, slightly cool deep magenta with the iridescent satin finish of structurally colored aragonite-nacre. The shell is the heraldic symbol of Saint James of Compostela.
