Coruscating Nymph Kelly

#27b540
Notes

Coruscating Nymph Kelly (#27B540) 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 (131°, 65%, 43%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Coruscating
adjective

Latin coruscāns, flashing — present-participle of coruscāre. As a color modifier, coruscating implies a saturated-and-rapidly-flashing quality, the bright color of lightning-strike atmospheric-electrical-discharge against the night-sky. Sits at the bright-and-flashing end of the grid, parallel to flashing and flickering in usage.

Nymph
modifier

Greek νύμφη, nature-spirit-and-young-bride. As a color modifier, nymph implies a nature-spirit-and-grove-and-spring quality, the visual register of Hellenic-nymph-and-grove-and-spring hand-nature-spirit-and-grove-and-spring Hellenic-nymph-and-grove-and-spring-and-Arcadian-pastoral nymph-and-nature-spirit-and-grove surfaces under Hellenic-nymph-and-grove-and-spring-and-Arcadian-pastoral Mediterranean-grove-and-stream dappled-grove-light. Sits at the modifier-and-myth end of the grid, parallel to dryad and nereid in usage.

Kelly
noun

A bright yellow-green named for the Irish surname Kelly, common enough by the late nineteenth century to stand in for generic Irish in American slang. The color is the saturated, optically bright green of a Saint Patrick's Day parade: cleaner than shamrock, brighter than fern, with the pop-culture weight of a color used annually for green beer, green carnations, and the Chicago River.

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.
