How do you get the color black without it being gray in color when added to white or not translucent and see through?

interesting question as even Molasses is only brown - not black

I'd like to know this too. Would love to have the recipe for the tar-like stuff they use on Messygirl.

If you add black tempera paint to chocolate cake batter it makes black sludge.

Heres a pic of me covered in the stuff. Be careful. Its hard to wash off.
