Ebon Aubergine

#4b1e70
Notes

Ebon Aubergine (#4B1E70) is a deep indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (273°, 58%, 28%) 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 lime. 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.

Aubergine
noun

The French and British name for the eggplant — borrowed from the Catalan albergínia and ultimately from the Sanskrit vātiṅgaṇa. Aubergine as a color name carries with it the slightly more aristocratic register of the European-language version of the word. The color refers to the same fruit as eggplant but shifted slightly redder in popular usage: a saturated, slightly red-shifted very deep purple with the polished finish of waxy fruit. Cooler than wine, warmer than indigo.
