Blood will however, take on a darker shade of red without oxygen, but it never goes anywhere near the color blue. If you would like to see for yourself, the next time you get a blood draw, or you donate…
The level of oxygen that your red blood cells are saturated with causes a conformational change in the hemoglobin. This conformational change also causes a change in its ability to reflect light. As a result blood that is highly oxygenated is a crimson red whereas blood that is relatively deoxygenated is more of a dark almost purplish color. As we typically draw from veins, the blood that is drawn is of a darker color.
