I use an add-on to RasMol Called RasMenu.  It greatly enhances the 
capabilities of RasMol.  In particular the color options.  I don't know 
were we got it, it's just out on our laboratory file server.  Has anyone 
else heard of this add-on?  If it's Shareware or Freeware I'll be happy 
to send you a copy (I need to check into it).  Just Reply if your 
interested and I'll have an answer in a couple of Days.
