How red will this permanent red hair dye show up on my black hair?

On the box, it shows the effect on 3 different shades of brown, but not black. But my hair isn't naturally black, it's a temporary dye. So... what do you think I should expect? Thanks. :)How red will this permanent red hair dye show up on my black hair?

DON'T USE THE DYE!! IF YOUR USING A TEMPO DYE THEN YOUR HAIR WILL GO BLONDE OR ORANGE I ADVISE YOU NOT TO USE THE DYE!!
You should try rising and shampooing it with hot water.
