Re: Fake or Nay?
Google is also common knowledge: "Blood is always red, veins appear blue due to light wavelengths being filtered differently by the skin. Blood is always red, actually. Veins look blue because light has to penetrate the skin to illuminate them, blue and red light (being of different wavelengths) penetrate with different degrees of success." Oct 16, 2012 Blood and veins are both red, veins appear blue ONLY when viewed THROUGH the skin. Geniuses everywhere these days |
