It depends on if you cut a vein or an artery.
Arteries carry oxygen-rich blood from the heart, veins carry oxygen-depleted blood to the heart.
So, if you cut a vein, oxygen-depleted blood, which is purple only when not exposed to oxygen will come out. And since there is no oxygen, it would stay purple.
If you cut an artery, the blood is already red, and assuming the oxygen in the blood diffuses into the vacuum, it would gradually turn purple as well. If the oxygen doesn't diffuse into the vacuum, then it would stay red.

Very dark red, but it would start boiling because if the high water content.
You can test this theory by putting a small amount of blood in a syringe, then pulling on the syringe plunger to create a vacuum inside.

A more important question is....how did you get your skin exposed to "outer space" in the first place?
If you had a cut, and it was exposed to the zero pressure of outer space, your insides would be sucked out of the cut. I would imagine this would create a beautiful palette of color.

Matters, if you still have oxygen around the area that was cut, it would stay the same color. But if there is no oxygen, it would be a darker shade of red.

Assuming, you can see the blood and the the light source contains red light the blood would appear to be red. If red light was not present, the blood would appear black - if you could see it at all.

Red, the same colour it is in your body. Blue blood is just a myth. Your veins/arteries look blue because they are underneath your skin. Plus your veins/arteries aren't the same colour as your blood.

I am assuming u mean outside a ship, but i think it would still be red... what other color would it be.... i asked my mom who is a doctor and she thinks that it would be red too.

Our interpretation of color is based on our sensory interpretation of light wavelengths.
Assuming your brain is functioning well, and artificial light is typical of that on earth, then you'll see the same as down here.
