Rugged Pourpre

#e55540
Notes

Rugged Pourpre (#E55540) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (8°, 76%, 57%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rugged
adjective

Old Norse rugga, rough / coarse — adjectival suffix -ed. As a color modifier, rugged implies a saturated-and-rough-and-weathered quality, the deep-rich color of Scottish-Highlands-and-Norwegian-fjord outdoor-and-mountain landscape. Sits at the bold-and-weathered end of the grid, parallel to tough and sinewy in usage.

Pourpre
noun

French for purple in its classical sense — the deep red-purple of Tyrian dye and the pourpre cardinalice of medieval French ecclesiastical dress. The color refers to a pourpre-dyed French silk: a saturated, slightly cool deep red-purple with the satin finish of plant-and-shell dye. The French cousin of porpora.

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.
