I have already read it and have started experimenting, but no time
to finish. At least it seems to work, if luacolor is loaded
before fontspec.
  The funny things I have seen:
* \pdfliteral direct0 g 0 G
  (missing curly braces around "0 g 0 G" of the \pdfliteral whatsit,
  inserted by luacolor).
* segementation fault in some configuration (hopefully I can repeat
  this scenario, because this is a LuaTeX bug).
