Lurid Endive

#64b710
Notes

Lurid Endive (#64B710) is a true lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (90°, 84%, 39%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lurid
adjective

Latin lūridus, pale-yellow / sickly — sharing root with lūror (yellowish-pallor). As a color modifier, lurid implies a saturated-and-shocking-and-sickly-bright quality, the bright color of Penny-Dreadful-and-Pulp-Fiction sensational-cover-art bright-and-pulpy printing. Sits at the bright-and-shocking end of the grid, parallel to garish and gaudy in usage.

Endive
noun

Cichorium endivia, the slightly bitter European chicory cultivated as a salad green since Egyptian times. The color refers to the inner leaves of a head of curly endive or escarole: a soft, slightly yellow-shifted green with the matte finish of dewy lettuce. Lighter than lime, more chromatic than celery, with the cool-weather association of late-fall greenhouse production.

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.
