the blood would be red not blue. oxygen would not change the color. the blue you see is you vein tissue. blood gets its red color b/c of the iron that is in it.

From Ask A Scientist (and other sources):
"Whole blood is not blue. It is either bright red (with oxygen) or dark red (without oxygen). Skin pigments and blood vessel coverings often make the blood seem bluish when looking at vessels on the skin."

Blood is never blue. The color of blood is due to an absorbance by the heme group of hemoglobin which depends on what ligands are bound to it. When oxygen is bound to hemoglobin, it has a bright red appearance. When CO2 is bound, as in venous blood, it has a darker red appearance.

Hi. Dark red. The bright red indicates that the hemoglobin is saturated with oxygen.

light red when oxygenated, dark red when deoxygenated.

Your blood would probably be blue, and then you would probably die form loss of it and from lack of air.
