I don't check the prompt before doing something. I use a green prompt on my local box, yellow when root locally, blue on servers, red when root on servers. Been doing it for years and it's become completely automatic to notice.
Throwing that away for the sake of a nice color scheme in Vim is suboptimal.
This kind of thing is why I just can't throw away my last 15+ years using a Linux terminal vs am iTerm or other OSX terminal... and the changes to the key mappings.
