Ignited Prehnite

#81c02f
Notes

Ignited Prehnite (#81C02F) 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 (86°, 61%, 47%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Ignited
adjective

Latin ignīre, to set on fire — past-participle of ignite. As a color modifier, ignited implies a saturated-and-just-started-burning quality, the bright color of match-strike-and-flint-spark initial-combustion emission. Sits at the bright-and-warm end of the grid, parallel to kindled and aflame 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.
