Why is oxygenated blood red?

The color of human blood ranges from bright red when oxygenated to a darker red when deoxygenated. It owes its color to hemoglobin, to which oxygen binds. Deoxygenated blood is darker due to the difference in shape of the red blood cell when hemoglobin binds to it (oxygenated) verses does not bind to it (deoxygenated).

Also know, why the blood is red?
