Why are blood vessels in our arms and legs green?
Depending on different oxygen levels, blood in different vessels has two different colors: freshly red and purplish red. After being loaded with oxygen in the lungs, the blood is freshly red. The blood then carries oxygen to all parts of the body, becomes deoxygenated and turns purplish red. When deoxygenated blood flows through blood vessels under the skin of our arms and legs, the blood vessels look green.
