Red blood cells (also called erythrocytes) contain hemoglobin which carries oxygen and carbon dioxide around the body. It is the hemoglobin that gives red blood cells their characteristic color. When the red blood cell has plenty of oxygen, it appears reddish; when it doesn't have much oxygen, appears darker and bluish!
