What Color Is Blood. Venous blood (except in the pulmonary veins) is low in oxygen so the hemoglobin makes the blood have a dark red color. Once the blood has passed through the capillary beds of the lungs, the blood will be bright red with the hemoglobin saturated with oxygen gas.
The truth is, blood does change color--from bright red to dark red--but it never turns blue. The reason blood appears blue in the veins has to do with whether or not the blood is oxygenated, the nature of blood vessels and the way light reflects off of skin.
