No, blood is never blue. This was a misconception made by the fact that veins appear to be blue because of how light reflects off the veins from under the layer of subcutaneous fat that absorbs the rest of the light waves. Deoxygenated blood is a dark deep red and oxygenated blood is more of a bright red. Blood cells get their color from hemoglobin which is red in color. If a person were to take away the layer of skin from the vessel they would see that both veins and arteries are a similar translucent vessel.
