Blood is only red if it's been oxygenated. It's blue if there is no oxygen present. The greenish color you see is the blood that has already delivered its supply of oxygen to the organs and muscles and is headed back to get some more. The blue color of the blood when seen through the skin can sometimes look greenish.
