Effulgent Asparagus

#81b648
Notes

Effulgent Asparagus (#81B648) 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 (89°, 43%, 50%) 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.

Asparagus
noun

Asparagus officinalis, the cultivated perennial whose tender spring shoots have been a delicacy since Mediterranean antiquity — Apicius gives a recipe in the first century. The color refers to the tip of a fresh asparagus spear: a soft, slightly yellow-shifted green with the matte finish of a young plant stem. Cooler than pear, warmer than sage, with the seasonal weight of a vegetable available only briefly each year.
