Awesome thanks!

I got that code to work, although I'm not sure if the "how to use" instructions are quite right.

I'm not very familiar with Emacs Lisp, but I took a stab at it anyway.  I wasn't quite able to get it to work.  I'm not sure I understand how the buffer positions and markers.  Perhaps you have any tips for what's wrong? <>

(Presumably, you would also want to be able to turn on/off the colors, but I didn't try to figure that out yet).
