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 idea that oxygenated blood is red and deoxygenated blood is blue is a common misconception. In fact, human blood is never blue. It does change color depending on the level of oxygenation. In the arteries, where blood is fully oxygenated, it appears bright red, while in the veins, where the oxygen is depleted, it is a dark red. Blood derives its red color from hemoglobin, a reddish iron-containing protein that is found in red blood cells.
