Double the fun, part 2
You're still on an island where the natives are either truth tellers or liars. Half of them have blond(e) hair and half have brown hair, and hair color is unrelated to truthiness.
Again you step out of the scorching sun into a cool, shadowed alcove and see two natives whose hair color you can't identify. "Tell me about yourselves," you say.
Native A says, "At least one of us has brown hair."
Native B says, "At least one of us is a liar."
What are they?
