Configurable colors

[kutzi]

Would be nice to have the colors configurable.
I'm using black on white terminal and the yellow prompt is hardly readable for me.

Actually, I don't have good idea to solve this problem.
If I support configurable colors, the solution that I prefer provides some color patterns and we can switch these by environment variable.

If someone has better idea, please comment here 🙇

Thanks.

IMO 2 different themes (dark and bright) might be enough for 99% of all use cases

This is what I get with solarized light, makes it unusable.

Black on White is unreadable with yellow color. Dark/bright theme that can be set with ENV would be nice. Or use some standard colors like most other cli tools, not every cli tool has this issue.
