Gallant Choy

#66a31e
Notes

Gallant Choy (#66A31E) 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 (88°, 69%, 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

Gallant
adjective

Old French galant, brave / charming — present-participle of galer (to make merry). As a color modifier, gallant implies a saturated-and-chivalrous-and-confident quality, the deep-rich color of Three-Musketeers and Cyrano-de-Bergerac swashbuckling adventure tradition. Sits at the bold-and-chivalrous end of the grid, parallel to valiant and heroic.

Choy
noun

The Cantonese family of brassica greens — bok choy (white-stem), choy sum (flowering choy), gai lan (Chinese broccoli). Choy color refers to fresh bok choy leaves: a saturated, slightly cool yellow-green with the satin finish of fresh brassica. Cooler than spinach.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
