It ultimately depends on her mate/spouse/lover/ and his genetic makeup.
If he has blue eyes the probability of a blue eyed child is very high. If
her mate has brown eyes, then the probability of a blue eyed child
decreases and the probability of a brown eyed child increases. Eye color
should not be a test for paternity. There are far better-more accurate
tests available for that.
