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.
Arteries appear white because they have a thick muscular wall made of three layers and do not transmit the color of the blood. Veins, conversely, have a thin translucent wall that transmits the color of the blood inside, distorting the color slightly and making it bluish. If you look at a vein in the body you can see the blood flowing inside of it, and if air bubbles get in (from an IV or from an intentional opening of the vein) you can also see the bubbles through the wall of the vein.
