My all-white and all-black Ameraucanas are pure. My Wheaton and Buff hens have Ameraucanas characteristics, but the breeder I got them from didn't claim they were Ameraucanas. They all have pea combs, reddish brownish eyes, red earlobes, beards, slate blue legs with white feet bottoms, and their eggs are blue or green all the way through the shell. None of my hens have ear tuffs, which is a good thing, because I think ear tuffs are a characteristic of EEs. My rooster was all white as a hatchling, but he has a couple black feathers in his tail now that he's mature. He produces a lot of all-white chicks.
