Here is the buffer colors file I mentioned in xemacs-beta.
I would appreciate it of some people could look at it,
suggestions welcome.

To start buffer-colors for testing,
open the buffer-colors.el file and
evaluate whole buffer.

That will add a menu item,
    Options-->Display-->Buffer-Colors
which you can toggle to enable the program.

When enabled, it shows up in the menu:
        Buffers-->Buffer Colors
