Blood cell + oxygen = red.
Blood cell - oxygen = blue.
Red blood cells are the ones that carry oxygen, therefore, they are red.
There is no one color for blood, as its color depends on its oxygen content.
Blood is never blue. It's only red or darker red. Blood being blue while it's inside of us is a misconception. It's actually a bit of an optical illusion because of the way the light penetrates the skin, therefore we see our veins as being blue. Then some guy without a clue ran around telling everyone blood is blue.
This really isn't even up for debate. It's a fact. I urge anyone who thinks otherwise to learn a little bit about the human anatomy. There's all kinds of fascinating misconceptions that people have.
Which is interesting to me, because of all the subjects one could want to learn, how one of them isn't the human body is beyond me.
