Hardy Macaw

#55a41f
Notes

Hardy Macaw (#55A41F) is a true lime with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (96°, 68%, 38%) 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

Hardy
adjective

Old French hardi, bold / brave — past-participle of hardir (to make brave). As a color modifier, hardy implies a saturated-and-cold-resistant quality, the deep-rich color of Scandinavian-and-Russian boreal-forest-and-tundra outdoor-clothing. Sits at the bold-and-resilient end of the grid, parallel to tough and resilient.

Macaw
noun

The genus Ara — large neotropical parrots — particularly A. militaris (military macaw) whose plumage is dominated by saturated green. The color refers to a military macaw's wing covers: a saturated, slightly cool deep green with the matte finish of structural-and-pigment feather color. Cooler than parakeet.
