Araucana, ameraucana, and cream legbars will lay a more sky blue egg, and only blue. EEs will lay varying shades of blue and green, and depending on the mix can even lay pink. There is a lot of variety in these birds, and they come in a lot of different color patterns, but they are not recognized by the APA as a pure breed. I have no problem with Easter Eggers. I love mine. I called them Ameraucanas when I bought them. I learned that they were Easter Eggers on BYC. I call them Easter Eggers now, because I want to be honest with my customers when I sell chicks.
