Burning Parakeet

#81bb27
Notes

Burning Parakeet (#81BB27) is a true lime with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (84°, 65%, 44%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Burning
adjective

The progressive participle of burn — used as a color modifier for hues that read as actively luminous, as if combustion is in progress. Burning red, burning orange: the implication is high saturation combined with thermal heat. Sits in the bright-and-warm corner alongside hot and flame. Slightly more active than smoldering.

Parakeet
noun

The smaller members of the parrot family — particularly Melopsittacus undulatus, the Australian budgerigar that became the world's most-kept pet bird. The color refers to a typical green-form budgerigar's plumage: a saturated, slightly yellow-shifted green with the matte finish of carotenoid-and-structural feather color.

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.
