Plutonian Aronia

#680c6b
Notes

Plutonian Aronia (#680C6B) is a deep violet 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 (298°, 80%, 23%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Plutonian
adjective

From Pluto, the Roman god of the underworld (Greek Plouton). As a color modifier, plutonian implies the cool deep darkness of the underworld realms, with literary-classical register. Sits at the deep-and-cool end of the grid, parallel to Hadean and cooler than infernal.

Aronia
noun

North American chokeberry (Aronia melanocarpa) — a Rosaceae shrub native to eastern North America whose deep-violet drupes are the most polyphenol-rich of any commonly cultivated berry. Aronia color refers to a freshly picked Aronia melanocarpa drupe-cluster: a saturated, slightly cool deep violet with the matte finish of anthocyanin-and-tannin-rich chokeberry. The genus name comes from the Greek aría, small fruit-bush.

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.
