MS Edge, almost working colors

[jcjolley]

It looks like Edge engine (not the new Chromium edge) almost has support for colors now, 3 years after #417
Could we revisit enabling them / If I submit a PR would it be considered?

I don't use or have Edge so if you can prove the colors work now then absolutely :)
