When I first tried the pre-release of the upcoming tox rewrite, I noticed tox itself has funky new colors - which I like a lot…

why has this changed
Honestly, I am not 100% sure.
But I know how to get the colors back.
All you need to do is changing this line commands = pytest {posargs} in your tox.ini,
to this line commands = pytest {tty:--color=yes} {posargs}.
This forces pytest to produce colorful output,
even when invoked without a tty attached.
And this is possible the why - pytest is called internally in a different way? Maybe?
