araucana and ameraucana are pure bred colored egg layers. What the hatcheries advertise are not actually these breeds but a mix which people call the easter eggers. EE can be anything and crossed with anything. They just carry the colored egg gene from probably originally having some araucana or ameraucana blood. So long as they lay colored eggs you can call it an EE no matter what breeds are in it. That's why they can have all sorts of personalities.
Again easter eggers are mutts and can look like anything too. I've got some bantam EE eggs in the hatcher from a lady that had many different colors. Hatchery EE I've seen though tend toward a standard mixed brown color. Like various shades of this one http://theraleyfamily.com/chickens/condo_crew/just_arrived/F.JPG
Most breeds have lots of different colors. Some colors are rare and worth more than others. Try http://feathersite.com/ for pictures of various breeds and colors or search the breed in google and hit images.
