Wired Groen

#51aa16
Notes

Wired Groen (#51AA16) is a true lime with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (96°, 77%, 38%) 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.

Groen
noun

The Dutch word for green — used for the Hollands Groen of Delft Blue's complementary glaze and the green polders of Dutch reclaimed-land farmland. The color refers to a Delft-pottery green underglaze: a saturated, slightly cool green with the matte finish of fired tin-glaze. The Dutch cousin of green.
