Quickening Yomogi
Quickening Yomogi (#5FB42E) 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 (98°, 59%, 44%) 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
Old English cwic, living / lively — present-participle of quicken. As a color modifier, quickening implies a saturated-and-coming-alive-and-active quality where the hue accelerates visual engagement. Sits at the bright-and-active end of the grid, parallel to animated and invigorating in usage.
Artemisia indica, Japanese mugwort — used in yomogi-mochi (mugwort rice cakes) and as a traditional moxibustion herb. Yomogi-iro refers to the slightly muted yellow-green of fresh mugwort leaves: a soft, slightly muted yellow-green with the matte finish of pubescent leaf surface. Drier than wakaba.

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.
