Blood has a red color when oxygen attaches to the hemoglobin. Thus, when blood is rich in oxygen (after it leaves the lungs) it is red, but when it is not carrying oxygen blood has a blueish tint to it and it is not red anymore. If you are cut and your blood is exposed to oxygen then the oxygen would attach to the hemoglobin giving its red color. In the blood donation bags there is traces of oxygen that binds to the hemoglobin, giving the donated blood its red color. So basically if, you were to cut yourself in space you whould more than likely be in the shuttle so the environment will have oxygen in it. Thus your blood would be red.

Base-state iron complexes, such as the hemoglobin in your blood, are a dark red (think rust, like on a piece of solid iron). When exposed to oxygen (or another highly "active" species, like certain poisonous gases) the iron at the center of the hemoglobin protein changes electronic state, which changes the way light is absorbed by it into a brighter red color.
The way to prove that blood is naturally a dark red is to look at it the next time you give blood or have blood drawn. The blood in the tube (which is sealed) is still red, but not bright red like from a cut.

Your blood would be red because although blood is blue before it comes in contact with air, blood passes through your lungs where it is oxygenated before going to your limbs thus is why it would be red if you cut yourself in space, considering that you are hooked up to some sort of oxygen supply while you are in space.

Red the blood would be red because you would be in an enviroment where oxygen would be made available or you would die! Blood is actually blue before it is exposed to oxygen.

well, your blood would boil and you would sort of evaporate in space because of the lack of pressure.
But assuming that this doesn't happen, some of your blood will be red and some of it will be blue.

blood is always red. it is never blue. it doesnt turn red when o2 hits it. its always red. if it only turns red with oxygen then why is it red while being pumped from your veins into a bag when giving blood?
