They are called red blood cells for a reason. They are generally red. If the amount of oxygen in the blood drops below a certain point, it can look purple, and through the skin the veins may appear to be blue.
Only in molluscs and some arthropods is oxygenated blood blue, due to the presence of the protein hemocyanin, which contains copper rather than the iron found in hemoglobin.
The cells in the bloodstream include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen to tissues, white blood cells help fight infections, and platelets aid in blood clotting.
