Hi Monkey!
There is a website that will help you. Just google "Ameraucana Breeders Club" and it will show lots of pics and describe the conformation to you. It even shows pics of each color in male and female.
Now, with ear tufts, I'll bet you're confused with the Araucana, which is a chicken that also lays a blue egg. They are often "rumpless--without the tail feathers", and tufted.
It's a very commonly confused topic. I have EEs myself (which my hatchery sold to me as Ameraucana), but I knew this. I did lots of research, and you will find the true Ameraucanas to be so beautiful, and they have specific colors.......
I still think my EEs are really gorgous, even though they're not a ture Ameraucana, and they do lay a very nice pale greenish/blue egg.
