Electric Glassy

#40f4b6
Notes

Electric Glassy (#40F4B6) 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 (159°, 89%, 60%) 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

Electric
adjective

From the Greek elektron, amber — the substance whose static-electric properties were observed by Thales of Miletus. Used as a color modifier since the late nineteenth century after electric light made certain saturated colors feel attention-demanding. Electric blue, electric pink: the implication is hot luminance combined with optical impact. Sits at the bright-bucket extreme.

Glassy
noun

A descriptor for very calm water surface — used in maritime vocabulary for sea conditions when wind is below 1 knot and the surface reflects like polished glass. Glassy color refers to a glassy-calm tropical lagoon at dawn: a saturated, slightly cool deep blue-green with the mirror-finish optical complexity of unbroken water.

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.
