Shimmering Mallard

#57ac3f
Notes

Shimmering Mallard (#57AC3F) 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 (107°, 46%, 46%) 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

Shimmering
adjective

Old English scimerian, to glisten — present-participle of shimmer, sharing root with shine. As a color modifier, shimmering implies a saturated-and-soft-flicker-reflective quality, the bright color of moonlit-water-and-silken-fabric surface-reflection. Sits at the bright-and-reflective end of the grid, parallel to glistening and glimmering in usage.

Mallard
noun

Anas platyrhynchos, the mallard duck — the most widespread duck species, ancestor of nearly all domestic duck breeds. The drake's iridescent green head is a structural color, not a pigment. Mallard color refers to a male mallard's head in breeding plumage: a saturated, slightly cool deep green with the iridescent satin finish of structural feather color.
