Color compatibility

[Danny Jared Epstein]

Dave Ungar and I were amazed that our evaluator ran in color the first tin though it was developed on a monochrome system.  It shows that the color in
SELF was implemented very cleanly.  Dave said that this was your doing, so you
should be congratulated.  Bravo!  The only part of the evaluator that is
sensitive to color/monochrome is the initialization (initColorParents /
initMonoParents).
