Can 2 blue-eyed parents produce brown eyes?

Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes it possible for two blue-eyed parents to have brown-eyed children.

Do blue eyes have blue pigment?

Can a baby have blue eyes if one parent has brown eyes?

Someone with brown eyes may be carrying one blue allele and one brown allele, so a brown-eyed mother and a blue-eyed father could give birth to a blue-eyed child. Now mix in a third green allele, which is dominant to blue, but recessive to brown.
