About Lime
Lime is a vivid light green. Its hue sits at 142° in OKLCH and 120° in HSL — the two wheels are spaced differently, which is why the numbers disagree.
The keyword lime is one of the sixteen original HTML 4 colors, the whole palette of CSS 1, so it is understood by every browser and every email client ever shipped.
Lime is the pure #00ff00 of a screen’s green channel — what the X11 list calls green. CSS green is the darker #008000 inherited from HTML 4, which is why both lime and limegreen are brighter than green.
