Thanks for finding the picture bigboy!
With the vein colors, they are a base with a top coat. Generally top coats are trans colors where they base coat gets to show through them, blue, red, gold, yellow, pink, and a few others are trans-colors. The vein is a silver black base, and I will have to see if they make it in white, instead of black. The only thing I would be afraid of is that the white will take on the color of the translucent, just like the silver does.
