Shadowy Aronia

#25043d
Notes

Shadowy Aronia (#25043D) is a deep indigo 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 (275°, 88%, 13%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Shadowy
adjective

Old English sceaduwig, full of shadow — adjectival form of shadow. As a color modifier, shadowy implies a deep-and-obscured quality where the hue is partially-occluded by intervening shade. Sits at the deep-and-veiled end of the grid, parallel to shaded and cloaked in usage.

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.
