Animated Quad Kelly
Animated Quad Kelly (#18B43B) 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 (133°, 76%, 40%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin animātus, given-life — past-participle of animāre, derived from anima (soul, breath). As a color modifier, animated implies a saturated-and-life-given quality where the hue carries visual movement-and-vitality. Sits at the bright-and-active end of the grid, parallel to spirited and lively in usage.
Latin quadrum, square. As a color modifier, quad implies an Oxford-and-Cambridge-college-quadrangle quality, the visual register of Oxford-and-Cambridge-college-quad hand-built four-sided-college-courtyard quad-and-cloister-and-lawn architectural surfaces under Oxford-and-Cambridge college-quadrangle academic light. Sits at the modifier-and-architecture end of the grid, parallel to court and atrium in usage.
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.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
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.
