Voodoo is an amazing color!  It’s a cross between gunmetal and pewter with the smallest hint of purple and green.  The first coat is so sheer I thought that this color would be awful, but after the second coat I realized you need to really load the brush up with polish if your nails are long.  I had a problem with balding if I didn’t let it completely dry between coats.  Below is 1-3 coats from left to right and a swatch of 3 coats.
