All this will break readline, because it includes non-printint characters.
It wont know how wide the terminal actually is and will do cursor ups
and stuff at the wrong time.

So yes, it is basically that it has the wrong idea of terminal size.

zvt doesn't hav e aproblem with that.

 \033[0m 

will reset terminal attributes.

Try perhaps putting a newline in the prompt, afte rthe colour stuff.
Otherwise, stick to a plain prompt.
