Wired Prehnite

#81b610
Notes

Wired Prehnite (#81B610) 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 (79°, 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

Wired
adjective

Old English wīr, wire — past-participle of wire. As a color modifier, wired implies a saturated-and-electrical-charged-and-active quality, the bright color of Tesla-coil-and-Van-de-Graaff high-voltage atmospheric-electrical emission. Sits at the bright-and-active end of the grid, parallel to charged and electrified in usage.

Prehnite
noun

A calcium-aluminum silicate gem — yellow-green, often translucent, mined principally in Australia, Mali, and Scotland. The color refers to a polished Australian prehnite cabochon: a soft, slightly cool yellow-green with the cloudy translucency of low-grade gem material. Cooler than peridot.

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.
