Aristocratic Vihreä

#377f0d
Notes

Aristocratic Vihreä (#377F0D) is a deep 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 (98°, 81%, 27%) places it in the highly saturated band at a dark 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.

Vihreä

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.
