Kojima apparently didn't think there'd be a game beyond MGS1, so these details hadn't been set in stone. From memory I'm fairly certain that Kojima didn't expect there to be any games past Metal Gear 1.

But as we all know, Kojima is not afraid of retconning details, so why not physical traits? I don't think there's anything to be said about Big Boss' appearance in MGS4, I think it was just to better reflect his Metal Gear and Metal Gear 2 appearances. And as for why his eyes are brown--maybe they just didn't fact check. He was also rebuilt from Solidus and Liquid (though I don't remember their particular eye colours either) sd that may have something to do with it.

Or we could even use the classic Metal Gear cop out; nanomachines.
