Id say no. Satanists don't always dress in black and such like the emo style. So just cause its completely black doesn't make it Satanist's. They like red as well.

You can't tell really evil people by what they wear.

I don't think there's much of a difference between them. All of them contain over 90 percent acetone with some minor ingredients that do who-knows-what. Pro nail techs generally use plain acetone they buy from a beauty supply or from a hardware store. So...if you like the idea of a nail polish remover that comes from a nail polish remover company, go to the drugstore and choose your favorite color of it. If you just want to strip the polish from your nails as cheap as possible, go to Home Depot or Lowe's and buy a quart of acetone.
