I've updated the face definitions to check for such capabilities, and
tested it in xterm (256 colors) and the Linux console (8 colors
according to `display-color-cells').  It looks good with my pair of
eyes, but I sometimes have a hard time differentiating between certain
colors.

If anyone feels that they are good with colors, feel free to suggest
something better.

I've attached a new patch.

Yes, that makes sense, changed in the attached.

Thanks for reviewing this.
