Glittering Fern

#61a551
Notes

Glittering Fern (#61A551) 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 (109°, 34%, 48%) 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

Glittering
adjective

Old Norse glitra, to shine — present-participle of glitter. As a color modifier, glittering implies a saturated-and-multi-point-reflective quality, the bright color of sequined-and-rhinestone fabric-and-gem-decoration surfaces. Sits at the bright-and-reflective end of the grid, parallel to sparkling and glistening in usage.

Fern
noun

The Polypodiopsida — vascular spore-bearing plants that dominated terrestrial flora during the Carboniferous, when their compressed bodies became most of the world's coal. The color refers to the upper surface of a healthy mid-summer fern frond: a saturated, slightly muted green with the matte finish of mature pinnae. Deeper than moss, cooler than chartreuse, with the patient persistence of a plant family three hundred million years old.
