Better theme compatibility for TUI

[akarray]

First of all, congratulations on this great project. It's really useful for the Omarshy distribution!
One important point to consider is improving theme compatibility.

For example, the TUI currently isn’t usable with the Floxoki Light Theme, as shown in the screenshot below.

Thank you again for your awesome work and for sharing this project with the community!

Thank you so much for the helpful feedback!

I’ve been wanting to improve compatibility with Omarchy themes, but I wasn't quite sure how to implement it, so I had put it on the back burner.

I’ll look into the methods again and take another shot at it!
