That is why they color them blue. And then the arteries, which usually carry oxygenated blood, are colored red. In real life, your veins look blue because of the other tissues that have pigments in them that you have to look through to see your veins. Even though they appear on the outside to be blue, in fact, on the inside they are carrying deep dark red blood. Just look at the vial of blood the next time the nurse draws some for a test.
