It might help to see the logo.

If the logo is white and the background is black, place the bitmap on a white page, and apply Flat, Multiply (Stained Glass) transparency and adjust the amount. The more transparent the lighter the black will be. When you have it the way you want it, the create a bitmap copy, True Color (but NO alpha)

Or select the bitmap, open the Color Editor and adjust the Dark Contone Color.
