A pink egg is really a pinkish brown egg. I've had an EE/BR cross pullet that laid a pinky colored egg with lavender speckles, but her sister laid a yellowish-beige egg. Same parents. No one can claim they sell only pink egg laying EE's. The mixed parentage negates any reliability in predicting the egg color, IMO. I have a Barred Easter Egger. Her mama is a blue Ameraucana and her dad a BR. She lays a green egg. All of my Barred EEs should lay green eggs. Blue+ Brown= Green. Any hen will lay the same color egg every time, but it may be lighter on occasion or near molt. Not sure I've answered the question you posed, though.
