Refulgent Aloe

#99c434
Notes

Refulgent Aloe (#99C434) is a true lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (78°, 58%, 49%) 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

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.

Aloe
noun

Aloe vera, the succulent whose translucent inner leaf gel has been used as a cosmetic and medicinal salve since classical antiquity. The color refers to a fresh aloe leaf in cross-section: a soft, slightly cool yellow-green with the satin finish of succulent leaf-tissue.
