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.
Oxygenated and Deoxygenated Blood. Blood cells have a protein called hemoglobin, which binds with oxygen and gives blood its characteristic color. Hemoglobin is also a part of skin pigmentation and gives skin its reddish undertones. When red blood cells pick up oxygen from the lungs, the hemoglobin turns the blood bright red. This bright red blood flows through the arteries and feeds all of the tissues and organs in the body.
