That is tricky. Asuming you can breath through a tank, if your blood is rich or not in oxygen when it comes out it will be red or blue.

So, It is Red? It could be, Red blood only happens when your blood just gets the oxygen from the lungs. there is a chance when you get cut that the blood will be red.

So, it is NOT blue? no, your blood will most likely be blue becuase of the fact that you don't breath as much as you don't. Well, atleast I DO anyways.

I think both of them could be a answer but correct me if I am wrong.
