Chartreuse (color)
Chartreuse green (the web color known as chartreuse since the X11 colors were created in 1987 and then renamed the X11 web colors in 1991) is a web color that was named because it looked like the green color of a French liqueur called green chartreuse, made since 1764. Before 1987, this color was called yellow-green, but that name is now used for the web color "yellow-green", a medium dark shade of chartreuse green shown in the color chart below.
