Aglow Cuì
Aglow Cuì (#47BC23) 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 (106°, 69%, 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English on-glōwan, on-glow — sharing root with glow and gleam. As a color modifier, aglow implies a saturated-and-lit-from-within quality, the bright color of fireplace-and-jack-o-lantern interior-glow-lit warm-light emission against ambient darkness. Sits at the bright-and-warm end of the grid, parallel to glowing and aflame in usage.
The Chinese word for kingfisher — and the saturated blue-green of kingfisher feathers used in classical Chinese cuì-yū (kingfisher feather) imperial ornament. The color refers to a polished fei-cuì (jadeite-cuì) bangle: a saturated, slightly cool deep blue-green with the satin finish of imperial-grade jade.

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.
