have you ever had your blood drawn, or donated blood? the blood that is in the vial or bag is deoxygenated blood. it is a dark red, almost purple color.
our veins are actually a purplish red in color, but they just look blue through layers of skin

No. Blood is NEVER blue!!! I know several people have said that it is, but this is not true! If you want proof, think. If you have ever given blood, they prick your vein, where deoxygenated blood is returning to the heart to get more oxygen. What color is it? It sure isn't blue! I've given blood to the Red Cross many times, and have had blood taken for medical reasons, and I can tell you that I have never seen blue blood! Now, deoxygenated blood is a darker color red (almost maroon) than oxygenated blood, but it isn't blue. The reason why is because oxygen turns things red. Rust happens because of an oxidation reaction. The brownish-red spots that form on apples is also a form of an oxidation reaction. The veins appear to be blue because the blood is a darker color red, as I said, and when it's blended with the color of the walls of the vein, the veins look blue. Your blood is always, ALWAYS red.

RE:
Is deoxygenated blood really blue?

What Pooh said -- but, bear in mind that it's not really fully deoxygenated. Not all the hemoglobin molecules within the red blood cells give up their oxygen cargo when traveling in the circulatory system.

no, i dont think so. deoxygenated blood becomes dark red,
so dark until it looks like purplish.

For example snails have blue blood, because they have haemolimfa, not haemoglobin. The ferrum in haemoglobin (which keeps oxygen) causes that our blood is red.

No, it is a dull dark red, kinda brick colored. It appears blue through the layers of vessel tissue and skin.
