Is Human Blood Actually Blue or Red? [VIDEO]

My wife is a 'phleb' (short for phlebotomist) or a medical professional who draws blood. I once asked her about the myth that blood is actually blue, but turns red once it hits the air. She says she draws directly from the body and the color of the blood is a deep red. I just had to dig deeper.

In an episode of 'Big Questions' that are part of the You Tube Mental Floss series, Craig Benzine settles the argument once and for all about whether blood is ever blue.

The part that hits home for me is when he talks about light reflection and refraction that convinces us that the sky is blue. Basically, your blood looks blue through your skin, but is actually red and the sky's color is actually many different colors, not just blue.

I love science!
