Vivid Nettle

#90b620
Notes

Vivid Nettle (#90B620) is a true lime with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (75°, 70%, 42%) 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

Vivid
adjective

From the Latin vividus, full of life — used as a color modifier since the late sixteenth century for hues that read as luminous and saturated. Vivid red, vivid blue: the implication is that the color appears almost lit from within, with the optical brightness of a high-chroma surface in good light. Sits at the bright-bucket center alongside bright and electric.

Nettle
noun

Urtica dioica, the European wild green whose stinging leaves are blanched and eaten as soup, tea, and herbal tonic — a traditional spring tonic across European folk medicine. The color refers to fresh young nettle tops: a saturated, slightly cool deep yellow-green with the matte finish of pubescent stinging-leaf surface.
