we do know now! I re-read a few pages of The Fall of Reach. the one where you read about all the genetic experiments and the selection of children for the experiments. and it says that Dr. Catherine Halsey checks her data pad and sees the picture of John, spartan 117, master chief, whichever you wanna call him, that he has brown tousled hair. BOOYA. research skills are 1337 as hell. lol- I am such a freakin' geek. oh man.
