Charged Vihreä

#66ba00
Notes

Charged Vihreä (#66BA00) 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 (87°, 100%, 36%) 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

Charged
adjective

Old French chargier, to load — past-participle of charge, sharing root with cargo. As a color modifier, charged implies a saturated-and-electrically-loaded quality where the hue carries visual potential-energy. Sits at the bright-and-active end of the grid, parallel to electrified and energetic in usage.

Vihreä
noun

The Finnish word for green — used for the saturated green of Finnish summer forests and the green-and-blue of the Finnish suomenlippu national flag's lake-and-forest symbolism. The color refers to a Finnish boreal forest understory: a saturated, slightly cool deep yellow-green with the matte finish of moss-and-undergrowth.

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.
