Effulgent Tabbouleh

#64b835
Notes

Effulgent Tabbouleh (#64B835) is a true lime 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 (98°, 55%, 46%) 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

Effulgent
adjective

Latin effulgēns, shining-out — present-participle of effulgere, sharing root with fulgor (lightning). As a color modifier, effulgent implies a saturated-and-radiating-light-out quality, the bright color of Renaissance-Madonna halo-and-aureole gold-leaf-and-pigment emission. Sits at the bright-and-saturated end of the grid, parallel to resplendent and radiant in usage.

Tabbouleh
noun

The Levantine bulgur-and-parsley salad — primarily fresh flat-leaf parsley with mint, tomato, lemon, and olive oil — traditional across Lebanese, Syrian, and Palestinian mezze tables. Tabbouleh color refers to fresh-chopped parsley in a tabbouleh: a saturated, slightly cool deep yellow-green with the matte finish of chopped fresh parsley.

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.
