Ebon Petunia

#5a154b
Notes

Ebon Petunia (#5A154B) is a deep magenta with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (313°, 62%, 22%) 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.

Petunia
noun

Petunia × atkinsiana, the modern garden hybrid bred from South American Petunia species in the nineteenth century — now the most-planted annual bedding flower in North America. The color refers to a deep purple petunia in summer container bloom: a saturated, slightly red-shifted deep purple with the satiny finish of trumpet-shaped flowers. Cooler than orchid, warmer than violet, with the bedding-plant weight of a genus bred for nearly endless color and continuous bloom.

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.
