Sure Lemongrass

#306c25
Notes

Sure Lemongrass (#306C25) is a deep 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 (111°, 49%, 28%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Sure
adjective

Old French seur, certain — used as a color modifier since the medieval period for hues that read as confident and stable. Sure red, sure blue: moderate saturation combined with optical commitment. Sits at the crisp-bucket center alongside steady and true.

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.
