Flashing Lemongrass

#99e05b
Notes

Flashing Lemongrass (#99E05B) 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 (92°, 68%, 62%) 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

Flashing
adjective

Old English flasch, flash — present-participle of flash. As a color modifier, flashing implies a saturated-and-rapid-on-off quality, the bright color of emergency-vehicle and photographic-flash light-burst surfaces. Sits at the bright-and-flashing end of the grid, parallel to coruscating and flickering 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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
