Resounding Mûre

#831fa4
Notes

Resounding Mûre (#831FA4) is a true 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 (285°, 68%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Resounding
adjective

Latin resonāre, to echo back — present-participle of resound. As a color modifier, resounding implies a saturated-and-echoing-and-imposing quality where the hue reverberates visually like a cathedral-bell ring. Sits at the bold-and-resonant end of the grid, parallel to resonant and booming in usage.

Mûre
noun

French for blackberry / mulberry (Rubus fruticosus / Morus nigra) — the deep-violet aggregate-drupe of European hedgerows and Morus tree-fruit, both important anthocyanin-rich autumn fruits. Mûre color refers to a freshly picked Rubus fruticosus aggregate-drupe in a Berry hedgerow: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich aggregate-drupelet cluster on hand-collected fruit.

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.
