Coloring problem in Prolog

Reading the coloring problem in Prolog, I was wondering whether it would be possible to tell Prolog that if @different(red,green)@ then one could infer that @different(green,red)@.
However, I tried defining the rule that @different(A,B) :- different(B,A)@, but running the program then never terminates.
How could I define such a rule?
