Your blood is red becouse there is iron in it. Many vital organs need iron to work. So I think you can really mess up your body when you change your blood colour. But I'm not saying this is not possible. There are actually animals living on this planet with different coloured blood, like blue or green. But as I said, you can mess up your whole body when you change your blood.
