The fat under your skin absorbs low frequency light - reds, and yellows. Only the more energetic light is reflected from the vein, the blues and purples. On the surface of the skin, this gives veins a blue/purple look, but if you were to cut the skin and fat away, the vein would be a dark red, the same colour as the deoxygenated blood inside.
Inside your body, blood is blue. Therefore your arteries and veins appear blue through the skin. Your blood turns red outside of the body because oxygen gets into the blood. The oxygen changes your blood's color from blue to red.

inside the body blue outside the body red
Frequently the answer is "blood is blue inside us and red when it hits the air". Blood carries oxygen in our body so this really doesn't make sense. Blood is red with arterial blood being brighter and venous blood being darker. Our blood vessels have a bluish appearance through our skin but just as water going through PVC piping isn't white, blood isn't blue.
blood is blue inside the body . kenzi is a noob.
Our blood is not blue when in the body. Many people think that because they assume that we don't have oxygen,and when exposed to oxygen it turns red. This isn't true because we do have oxygen in our body. Without it inside we will be dead.
blood is red blood cells that help your body flush out the bad stuff. blood is blue when its inside you and when it mixes with oxegn it turns red.
The misconception of blood color arises from the fact that oxygenated blood appears bright red when it comes in contact with oxygen, while deoxygenated blood appears darker red when it lacks oxygen. People often think blood is blue inside the body because veins appear blue due to the way light penetrates the skin.
it is blue inside your body but outside when it gets air it is red so veins r blood n veins r blue so yeah
