What is the best way to make an OMP/built in theme use only the Terminal Colors instead of it's own custom ANSI/HTML color codes?

[Derpitron]

I like the emodipt-extend theme's prompt, but I want to use my own terminal's color codes for it, as I switch between the Nord and Gruvbox theme at my whim.

Is there an easy way to do this, or any way at all?

You can use the default 16 ANSI color names. They will be the same reference.

Looks like manual find-and-replace it is, then
