deoxygenated blood looks slightly purple/blue as the fe^2+ prosthetic groups in the erythrocytes (red blood cells) are not bound to O2. when they are, they appear the colour red that is seen when blood is exposed to the air.

Why is it said royals have blue blood?
If you look at the wrist of an untanned caucasian person, the veins there look almost blue. Royalty were usually shaded when out in the sun, by servants and the like. Thus, royalty were believed to genuinely have blue blood.

If your blue veins are showing in your wrists is that a sign your period is coming or is that a sign of pregnancy?
First, ALL blood vessels just under the skin look blue. Blood vessel color, or whether flatter or puffier, is NOT a pregnancy symptom. You might be confusing facts with a later pregnancy sign, when blood vessels in the breasts engorge (e.g. the vessels look bigger). Blood vessel color, size, or appearance anywhere that vessels are seen through the skin also has nothing to do with menstruation.

Which blood vessel has blood color?
All vessels containing blood would have red blood; in arteries and in veins and smaller vessels.The blue appearance of veins is an optical illusion that comes from the way light works on skin. The veins look blue because they are closer to the surface, if arteries were not as deep, they would look blue, too. It has nothing to do with oxygenation of blood in arteries and all to do with the properties of light and skin.
How deep are the arteries in your wrist Am I seeing the veins or the arteries when I look at my wrist How deep would I have to cut to hit an artery?
The Related Links section has a link to a website that has a diagram of the arm.The bluish blood vessels visible when you look at your wrist are veins. The arteries are deeper and not located particularly near the veins. Gray's Anatomy has a transverse section of the wrist; if you look at it you'll see you'd have to cut fairly deeply to hit one of the arteries, and the other is buried behind a ligament.
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.
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.
Why do your vains look blue?
your veins look blue because your blood has no oxygen, when your blood is oxygenated it is red and when it is deoxygenated it is blue. veins carry blood toward the heart and are often blue while arteries carry blood away from the heart and are filled with oxygenated blood.
