Established Pourpre

#e61500
Notes

Established Pourpre (#E61500) is a true red with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (5°, 100%, 45%) 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

Established
adjective

Latin stabilīre, to make stable — past-participle of establish. As a color modifier, established implies a saturated-and-rooted quality where the hue carries the weight of long-standing visual presence. Sits at the bold-and-firm end of the grid, parallel to steadfast and anchored 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.

Wide gamut

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.
