I'm pretty new too but I happen to know the answer to this question! More experienced members, correct me if anything I say is wrong here.
An Easter Egger is generally a cross between an Ameraucana and a brown egg layer (Plymouth Rock or Rhode Island Red, for example). They are not show quality, but are super cute with puffy cheeks!

They're a smallish breed and can be just about any color, from brown to gray to white. Mine is a pretty light brown/gold. If you google Easter Egger you'll see what they can look like.
Generally they lay green or blue eggs, but because they're a cross, anything is possible. They can lay pink or even brown eggs, though it's rare. (Just like other breeds, though, they won't change the color of the eggs they lay from day to day...if their first egg is green, they'll always lay green. That seems to be a common misconception.)
My EE is only five weeks old, so I can't tell you what color hers are yet. I love my EE and would highly recommend them, but if you're looking for a particular shade of egg color, an EE might not deliver what you want...or she might! They're unpredictable that way.
Edited to say that all this info is concerning the variety in the U.S. I'm honestly not sure if they're the same in the U.K. Others can chime in for that
