Well that depends on what colours the creatures are. You need to give example of creatures. Do you mean like Knight of Infamy and Knight of Glory?
If the blocking creature is black, then it can't block. Protection from each other doesn't cancel out - a black creature can't block one with protection from black, even if it has protection from the attacker.
