About Green
Green is a mid-tone 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 green 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.
CSS green is #008000, a half-intensity green. The full-intensity #00ff00 that the X11 list calls green is named lime in CSS, because HTML 4 had already given the word green to the darker one.
