About Chartreuse
Chartreuse (chartreuse) is a medium, vivid green with the hex code #7fff00, or rgb(127, 255, 0). In HSL it sits at a hue of 90°, 100% saturation and 50% lightness. It is one of the 148 named colors every browser understands, so you can write color: chartreuse; instead of the hex value.
