White.
You can only ever reduce the number of white balls by 2, never by 1 (if you take out one white and one black, the white is always returned). Thus sooner or later you will have a single black ball left in the pot, with an arbitrary number of black balls. At this point you will never throw away the white ball, hence the answer of white.
