Contrary to popular belief, the veins are not blue. The color of most blood is a transparent yellow which is due to the majority of blood being comprised of blood plasma (If you have seen blood centrifuged, you know what I am referring to). The hematocrit is the only part of blood that is red: dark red if deoxygenated and bright red if oxygenated. No blood is blue (inside the body or out). Dried blood which has no gaseous oxygen in it is still red (though a brownish red at that) because the iron in the bood is still rusted from oxidation. The red blood cells have iron in them due to the hemoglobin molecule in them. It is the iron in blood which attracts oxygen that gives it its red color. The reason why only veins appear blue is because they are the most superficial to the skin and therefore seen by the eye. Arteries can not be seen because of how deep they are in the body (a protective mechanism of our bodies). The color blue/violet is the highest frequency of the visible light scale; it therefore has the most penetrating power to be seen through skin, fat, etc. Red is low frequency and is filtered out by skin and fat, which is why it cannot be seen. If you took a red diode light and put it in milk, it would appear blue in color because milk filters the red out much like our fat/skin. Try it and see!

Does heroin still work if you miss a vein?
Yes. Hitting your vein allows it to get into your system much faster. Hitting another site, like fat, will still be absorbed into your system, just not as quick. I might even be toned down since it will be introduced into your system slower.
