There are many misconceptions when it comes to the color of blood. Most of them even sound so scientific that we should all be forgiven for being mistaken. Think over some of the things you’ve heard about blood in your life. Like the fact that blood is blue or purple when it’s inside your body or its color comes from iron and hemoglobin. But what’s the truth? What color is blood? Why is it the color it is? How about why it looks different when it’s inside your body than when you’ve grazed your knee?
Yes. Always. Blood is always red. It’s red when it’s inside of your body, coursing through your veins, and it’s red when it comes to the surface, too. There’s even a shade of red named after it, “blood red”! For some reason, a lot of us have heard down the line that blood is actually blue when it’s inside the body. It makes sense; our veins are blue, when you get varicose veins, they look purple. While the shade will change, blood is, undoubtedly, red.
