You should also check out the ABC (Ameraucana Breeders Club) website http://www.ameraucana.org/. They have photos of each of the recognized colors and breed specs. Very helpful. Yours are very lovely and the only deficit to having them over "true" Am.s is that you would be disqualified at a show. EEs make very nice pets, lay a good number of eggs, usually in a variety of blue to green shades and aren't to tough on the eyes either!
Here's one of the ABC's photos of a true white hen of their standard of perfection.
