if you're speaking of the dark blue / grey eyes on newborn pups.... they will become brown. exact shade is to be determined.
eta: my initial reply was referring to dogs with normal pigment. blue gsd are dilutes.... now seeing your other post I would say that his eyes would end up gold, however - if the puppy behind him is a littermate, based on his color I would question if the pups are purebred. if there is a chance that they're part husky, border collie, etc... then obviously the eyes will remain blue.
