I believe babies often have blue eyes that then can change color as they get older.
In looking for a close up earlobe picture of ANS ..I found one that shows why the men may be susceptible to her charms...ahem...yeah, it is a nude.

My understanding is that it doesn't take more than a few months for a baby's eye color to change. They are all blue at birth due to eye drops newborns receive but that doesn't last long IIRC.
