Another option that you may be interested in is colouring cell contents
based on what sort of info they contain eg formula, constant, inputs
etc. If so, check out Aaron's colour code macro:

which is listed on his page:

This is exactly the kind of thing I was hoping to accomplish (cell
coloring).
Thanks a lot!

P.S. I posted a reply a long time ago, but it never showed on this NG.
Strange!
This is a second try.
