Lustrous Ivy

#48b040
Notes

Lustrous Ivy (#48B040) 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 (116°, 47%, 47%) 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

Lustrous
adjective

From the Latin lustrare, to illuminate — used as a color word since the seventeenth century for hues with the slight specular shine of polished metal or silk. Lustrous green, lustrous gold: the implication is moderate-to-high saturation combined with surface reflectivity. Sits at the bright-and-glossy corner alongside gleaming.

Ivy
noun

The genus Hedera, the evergreen climbing vines of European woodland — English ivy, Algerian ivy, Persian ivy — colonizers of stone walls, oak trunks, and any abandoned masonry. The color refers to mature ivy leaves on a south-facing wall: a deep, glossy green with the high specular shine of waxy cuticle. Darker than spinach, cooler than holly, with the architectural association of a plant that wraps human structures back into landscape.
