Devout Parakeet

#57a427
Notes

Devout Parakeet (#57A427) is a true lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (97°, 62%, 40%) 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

Devout
adjective

From the Latin devotus, consecrated — used principally in religious contexts for the dignified deep colors of sacred art and ecclesiastical dress. As a color modifier, devout implies saturation combined with restraint: the deep blues of Marian mantles, the deep reds of cardinals' robes. Sits in the bold-and-formal corner alongside imperial.

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.
