Wired Bluegrass

#3fb358
Notes

Wired Bluegrass (#3FB358) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (133°, 48%, 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 magenta. 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.

Bluegrass
noun

Poa pratensis, Kentucky bluegrass — the cool-season turf grass that dominates lawns of the American Northeast and Midwest. Bluegrass music takes its name from the same plant via Bill Monroe's bluegrass-state Kentucky band. The color refers to a fresh-mown Kentucky bluegrass lawn: a soft, slightly cool blue-green-gray with the matte finish of cropped grass.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
