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.
Answer 1: Blood is red because it is made up of cells that are red, which are called red blood cells. But, to understand why these cells are red you have to study them on a molecular level. Within the red blood cells there is a protein called hemoglobin. Each hemoglobin protein is made up subunits called hemes, which are what give blood its red color.
