It would still be red. The reason blood is red in the first place is that it contains hemoglobin. Hemoglobin is a blood protein that contains the element iron. Iron in its atomic state is red. With the addition of oxygen it makes it a bright red. Red is red. Blood is never Blue. Many people have the mistaken belief they can see the blood in their veins. Since their veins look blue they think the blood is also blue. Veins are not transparent, They are actually made up of 3 different layers of muscle and connective tissue. Hardly transparent. The skin gives the veins its blue appearance.

The blood itself would still be red for a short period of time. Even though there is no oxygen in space there is oxygen in the blood itself. The oxygen combined with the hemoglobin in the red blood cells gives the blood its distinctive color. However many other factors would begin to instantly work on the blood. In a vacuum the moisture in the blood would boil off immediately, this would destroy most of the cells in the blood. At that point the Hemoglobin would be broken down and its red reflective chemicial composition would change. It would most likely then become like other dried blood that you have seen and not be red really at all, but more likely black.

Oxygenated blood is a bright, rich cherry-red; deoxygenated blood is a very, very dark red. The color is derived from the iron (heme) carrying hemoglobin molecules of red blood cells.
However, deoxygenated blood tends to absorb slightly more in the red end of the spectrum than oxygenated blood, and when combined with how long vs. short wavelengths are scattered when penetrating tissue, ends up making veins (carrying deoxygenated blood) appear blue when viewed through the skin.

In a no oxygen enviroment, if you sliced open an artery, obviously you are in a spacesuit and breathing, the blood would be red, your suit being ruptured would leak all oxygen and you would die. If you were in the same scenario as above but sliced a vein, it would be blue, but you would still die. It is only in the presence of oxygen our blood is red.

blood color is dependant on iron in the red blood cells.
even without oxygen, blood would be deep red in color.
If you are interested check out what component makes the HorseShoe crabs' blood really blue. Instead of iron its main component is... ? Scientists are studying this fact now.

I think it would be violet because blood turns a bright red when exposed to oxygen.

reddish and blue, your blood has oxygen in it. However, if you were in a spaceship, it would be red because there is oxygen in the ship.

Red.
Keep in mind your blood has oxygen in it.

Well, red because you'd still have to breathe oxygen to survive.
