Our Veins look blue as well because those veins contain carbonated blood ,the blood which is going back to liver for oxygenation or purification.
Due to access amount of carbon di oxide this blood looks like blue inside the veins.

∙ 8y agoBlood is always red, actually. Veins look blue because light has to penetrate the skin to illuminate them, blue and red light (being of different wavelengths) penetrate with different degrees of success. What makes it back to your eye is the blue light.

What color is veins?
Mostly a very dark brownish red, although when you look at them through many people's skin, they look blue. This is an illusion, caused by the reflective factors of the skin, that gives the appearance of blue. This pertains to the veins themselves and the venous blood; both look blue through the skin. Deep bruises look bluish red for this reason, we can see more of the red color since the blood of the bruise is closer to the surface than veins, that look very blue through the skin. The arteries are much deeper in the tissues where they are less visible and have less of the reflective factor involved, but they are also red. The blood in arteries is a brighter red than the brownish maroon color of venous blood. During vascular and endovascular surgery and direct visualization, the true red colors are visible.
What color is de oxygenated blood?
No. De-oxygenated blood is a dark red color. It may look blue in an anatomy and physiology text book, but the authors do that to show more clearly which blood vessels, usually veins, that carry de-oxygenated blood. 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. You will see that it is dark red.
