Tenacious Lemongrass

#428d31
Notes

Tenacious Lemongrass (#428D31) 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 (109°, 48%, 37%) 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

Tenacious
adjective

Latin tenāx, holding-fast — adjectival suffix -ous. As a color modifier, tenacious implies a saturated-and-clinging quality where the hue grips its substrate with stubborn pigmentation. Sits at the bold-and-resilient end of the grid, parallel to unyielding and adamant in usage.

Lemongrass
noun

Cymbopogon citratus, the tropical grass whose lemon-scented stalks flavor Southeast Asian curries, Thai soups, and herbal teas. The color refers to a fresh-cut lemongrass stalk in cross-section: a saturated, slightly yellow yellow-green with the matte finish of fresh grass-family fiber.

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.
