Wired Atacamite

#51f3b5
Notes

Wired Atacamite (#51F3B5) is a true teal with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (157°, 87%, 64%) 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 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.

Atacamite
noun

A copper-chloride mineral named for the Atacama Desert of Chile where it was first described. Atacamite forms in arid copper-mineral deposits worldwide. The color refers to a clean atacamite crystal: a saturated, slightly cool deep emerald-green with the satin finish of crystallized secondary copper mineral.

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.
