Be warned that the ANSI range is intrinsically limited to 240 colors and that not all intuitive operations will give good results.
Coolor doesn't contain functions to print on the terminal, but the colors can be used in other crates. There's an optional feature for conversion from and into Crossterm colors. You'll see it used in the included examples.
