Most probably brown. Everyone has contrib from each parent. You must be. GG. He can be BG or BB. Either would make his eyes B because B dominates. So if he is BB the baby is B. but if he is BG and he contributes his G, then the baby would be GG with G eyes.
It could be green or brown but it depends on your husband. If he has brown and green genes there is a fifty percent chance that you might have green. if he has only brown genes you will have brown eyed children every time. Green is recessive, so you only have green in your genes.
