Is it true that male lovebirds have blue pigments on either the ring in their eyes (for the eye-ring ones) or on their f

That's what I've heard

Yep its indeed true

It's because my male lovebird have blue pigments on his feet and also a bit on the ring in his eyes. Someone told me that those blue pigments have something to do with the gender. Is it right or are their scientific proofs that says it's true? In your lovebirds or other birds, do you see blue pigments? Are they male or female? Thanks a lot for the replies in advance.
