Alight Gorm

#66b446
Notes

Alight Gorm (#66B446) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (103°, 44%, 49%) 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

Alight
adjective

Old English ā-lihtan, to set alight — past-participle of alight. As a color modifier, alight implies a saturated-and-currently-illuminated quality, the bright color of Christmas-tree and Diwali-lamp festival-decoration illuminated-and-twinkling emission. Sits at the bright-and-warm end of the grid, parallel to aflame and aglow in usage.

Gorm
noun

The Irish word that historically spans both blue and green — gorm is the gray-green of stormy Atlantic seas, the soft green of Irish hillsides, and the deep blue of the Tír gorm (deep blue land). The color refers to an Irish hillside in fog: a soft, slightly muted gray-green with the matte finish of mist-shrouded grass.
