The latter (one argument) is what you have to use when the operator is a
member of a class (color, I suppose).  '* this' will be the 1st (= left)
argument then.  Use the former (two arguments) when the operator should not
be a member of any class -- this is what you may freely choose.

BTW I guess it would be more correct if you would return just 'color', not a
reference, but I'm not sure.
