Sparking Vihreä

#37ba1c
Notes

Sparking Vihreä (#37BA1C) is a true green with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (110°, 74%, 42%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sparking
adjective

Old English spearca, spark — present-participle of spark. As a color modifier, sparking implies a saturated-and-electrical-emission quality, the bright color of welding-arc-and-Tesla-coil high-voltage spark-discharge emission. Sits at the bright-and-electric end of the grid, parallel to flashing and coruscating 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.

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.
