Bleurgh! Remember, "the whole world is not a VT100". Or in this
particular case, the whole world doesn't support ANSI escape
sequences. Try instead:

	colour1=$(tput setf 3)
	colour2=$(tput setf 2)
	colour3=$(tput setf 3)
	colour4=$(tput setf 7)

That'll work, no matter which terminal you're on. Plus it has the
added benefit of not cluttering up your rc scripts with line noise...
