What color eyes will a baby have if the father has blue eyes and the mother has blue eyes?

Most likely blue eyes.
Blue eyes. Blue eyes are a recessive trait and the only way to have true blue eyes (not hazel blue or anything in between) is if bothe recessive genes are present. If there happens to be a touch of brown in those blue eyes then the eye color can vary.
Most likely blue, since blue is recessive.
The eyes will most likely be hazel or blue.
