Unyielding Aronia

#631695
Notes

Unyielding Aronia (#631695) 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 (276°, 74%, 34%) 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

Unyielding
adjective

Old English un- (negation) plus gildan (to give-up). As a color modifier, unyielding implies a saturated-and-uncompromising quality where the hue refuses to fade-or-shift under any visual pressure. Sits at the bold-and-resilient end of the grid, parallel to indomitable and adamant 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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
