When the oxygen binds to hemoglobin in the lungs, it offers blood a brilliant red color. Nevertheless, as the blood travels with the body and also oxygen is launched to the cells, the hemoglobin undertakes chemical changes that create the blood to appear darker.

In addition to the reduced oxygen degrees, the visibility of co2 also adds to the dark color of venous blood. Co2 is a waste product generated by cells during metabolic process. As the blood grabs carbon dioxide from the cells, it better modifies the color of the blood.
