But there are 2 issues:
1- make sure that default faces have a foreground that combines well
   with its background.  I.e. each individual char should be legible
   even for colorblind users.
2- try to use visually different appearances for different font-lock faces.

The first issue is very important (e.g. a requirement to enable
font-lock by default).  The second is very secondary in comparison.


        Stefan "and note that I carefully talk about the appearance of
                the faces, and not their color: most of my faces use the
                default foreground and background color and are
                distinguished by other attributes"
