The key to drawing realistic looking veins is in natural colors, and shadows and highlight.

Notice that the veins are usually darker than the rest of the skin. The blood underneath is typically blue. Work a little blue-green into your flesh tone. A LITTLE. If drawing in black and white, only a slightly darker tone is needed. You can almost do it with nothing but shadows and highlight.

Next, notice the shadows on the sides of the veins away from the light, and the highlight on the sides toward the light. Don't forget your reflected light at the base of the shadows, and you can also control the three-dimensional effect of the height of the veins off the skin, with more contast between the shadow and the light.

These principles apply to drawing most any three-dimensional object, especially those in relief.
