Well, I would say that the light pinky ones are the blues and the darker ones are the chocolates...although the runt almost looks black in that picture. lol
So in that last picture it kind of looks like chocolate, blue, black, blue, blue, chocolate.
To have a better idea, there needs to be better lighting in the pictures.
Also, it will be much easier to tell once they get more fuzzy hair in the next couple days.
