Forum:Crowfeather and Millie: eye color

What color are Crowfeather's and Millie's eyes, officially? Crowfeather's eyes start out being blue, then they change to amber in Twilight and Cats of the Clans, and then in Eclipse they are mentioned as green! What's going on? Millie's eyes are unidentified, too. On the manga books, she is shown with amber. In Cats of the Clans, she has green, and in one of the Po3 books it says in the allegiances she hs blue! It doesn't make any sense! What color are their eyes, really?
