Refulgent Tarragon

#4ebf14
Notes

Refulgent Tarragon (#4EBF14) is a true green with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (100°, 81%, 41%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Refulgent
adjective

Latin refulgēns, shining-back — present-participle of refulgere, sharing root with fulgor (lightning). As a color modifier, refulgent implies a saturated-and-reflective-shining quality, the bright color of polished-bronze-and-armor reflective-surface mid-day-sun reflection. Sits at the bright-and-saturated end of the grid, parallel to effulgent and resplendent in usage.

Tarragon
noun

Artemisia dracunculus, the French tarragon — small narrow-leaved relative of wormwood whose volatile oil tastes faintly of anise. The color refers to fresh tarragon leaves on the stem: a saturated, slightly muted green with the matte finish of a Composite-family leaf surface. Cooler than basil, lighter than spinach, with the kitchen specificity of a herb that defines béarnaise and a French roast chicken.

Wide gamut

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.
