Comment 1 for bug 1810595

A number of third-party Python modules are mentioned on https://stackoverflow.com/questions/287871/print-in-terminal-with-colors but it's also easy to do on most platforms without any external dependencies by using ANSI escape codes:

Auto-detecting support for ANSI colors is pretty hard:

and so it may not be worth it.
