Candidates are opposite when only one of them must be true, while the other must be false. They have opposite parity within a cluster.
In coloring, colors represent parity. Since there can only be two colors in a single cluster, one of them must belong to the solution, while the other does not. All candidates with the same parity are equivalent.
