Please describe the problem you're trying to solve

The terminal color auto-detecting doesn't work in tmux popup windows.

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

It'd be great if the color theme could be manually set with either a flag or an environment variable!
