@Zanna I think that there is some useful info in both answers. I'll test it a bit later and I will either improve the non-deleted one, or I will write an answer myself.
@Zanna After reading the linked article, there is no suggestion there for how to change the prompt's color, which is what the question asks. So I think I will write an answer also based on this similar SO thread I found.
Yeah. However the OP actually found the answer, as shown in their comment in the deleted answer, but they couldn't make the change permanent. So the new answer addressed that.
Hmmm. Now that I wrote that, I don't know what to do. Write an answer or improve the newer?
