Fortified Peony

#b5178b
Notes

Fortified Peony (#B5178B) is a true magenta with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (316°, 77%, 40%) places it in the highly saturated band at a mid 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

Fortified
adjective

Latin fortificāre, to make strong — past-participle of fortify. As a color modifier, fortified implies a saturated-and-strengthened-and-defensive quality, the deep-rich color of Vauban-style military-fortification stone-and-earth rampart-and-bastion architecture. Sits at the bold-and-fortified end of the grid, parallel to bastioned and armored.

Peony
noun

The genus Paeonia — herbaceous and tree peonies cultivated in Chinese gardens since at least the seventh century, where the flower symbolizes prosperity and is sometimes called the king of flowers. The color refers to a deep-pink peony at peak bloom: a saturated, slightly cool deep pink-magenta with the satiny finish of multi-petaled flower form. Cooler than coral, warmer than orchid, with the cultural weight of a flower that names imperial-Chinese reign periods.

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.
