Refulgent Bee-eater

#57f1d9
Notes

Refulgent Bee-eater (#57F1D9) is a true teal with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (171°, 85%, 64%) 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 red. 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.

Bee-eater
noun

The family Meropidae — Old World bee-eaters whose males display saturated blue-green plumage with chestnut and yellow markings. The color refers to a male European bee-eater's wing: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored feathers.
