Your blood is actually always red! Blood in your veins has very little oxygen and is a dark red color that looks almost blue when covered by your skin. Your arteries have bright red blood because it has a lot of oxygen in it that is being carried throughout your body to be used by tissues.
Why do my veins stick out and show so much? I am only 17, and my veins in my hands, arms, and feet all like drastically show? what is wrong with me! the veins are like blue/green and puffy! it has always been like this, just wondering why it really bothers me..could be just because im pretty skinny?? because im also prettyy boney..eport Abuse. You just have big veins and good blood flow. I'm not skinny and mine show the same way. Don't worry about it, besides, if you ever have to have a blood test or IV, they won't have any trouble getting into yours. Drinking to much water will also make you veins pronounced.
