Pulsating Flit Chartreuse
Pulsating Flit Chartreuse (#C5DF7A) 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 (75°, 61%, 68%) 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
Latin pulsātio, beating — present-participle of pulsate, sharing root with pellere (to drive). As a color modifier, pulsating implies a saturated-and-beating-and-rhythmic quality, the bright color of rave-and-festival light-show synchronized-pulse rhythmic-emission. Sits at the bright-and-active end of the grid, parallel to throbbing and strobing in usage.
Old Norse flytja, to-move-or-shift. As a color modifier, flit implies a quick-darting-and-light-winged quality, the visual register of swallow-and-warbler-flit hand-quick-darting-and-light-winged swallow-and-warbler-and-darting-finch flitted-and-quick-darting-and-light-winged surfaces under swallow-and-warbler-and-darting-finch summer-eaves-and-hedgerow-and-meadow-edge dappled-flight-light. Sits at the modifier-and-mood end of the grid, parallel to hover and flutter in usage.
The yellow-green French liqueur made by Carthusian monks at the Grande Chartreuse monastery since 1737, from a recipe of 130 herbs known to only two living monks at any time. The color is the base spirit chartreuse jaune in a glass: a saturated, slightly green yellow that's brighter than lemon and warmer than lime. The liqueur gave the color its name, not the other way around.

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.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
