Forthright Limetta

#669b1f
Notes

Forthright Limetta (#669B1F) 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 (86°, 67%, 36%) 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.

Limetta
noun

The Italian name for bergamotCitrus bergamia — the tart citrus fruit cultivated in Calabria for the essential oil that flavors Earl Grey tea and eau de Cologne. The color refers to a fresh-cut bergamot at peak ripeness: a saturated, slightly cool yellow-green with the matte finish of citrus rind. Cooler than limone.
