Is there red blood in the arteries and blue blood in the veins?

In textbooks, arteries are often colored red while veins are colored blue. This is just to distinguish between oxygenated and deoxygenated blood for demonstrative purposes. In fact, all blood is red. Oxygenated blood is a brighter red while deoxygenated blood is a darker red color. This has to do with the higher levels of oxygen bound to hemoglobin in arterial blood vs. the higher amounts of CO2 in venous blood.

Our blood vessels appear blue through our skin because the lower frequency light is absorbed by our skin, while higher frequency light is reflected back to our eye. Blue is perceived from a higher frequency light wave.
