Why does the blood in the veins appear bluish?
The blood in veins appears bluish because of how light interacts with the skin and the blood vessels. The oxygen-depleted blood in veins absorbs more red light and reflects more blue light, giving it a bluish hue when seen through the skin.
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.

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.
