Ah no. The black stone was 99 % the local sandstone. It is yellow-brown in the beginning, but over the years it gets black.

The reconstructed Frauenkirche is a mixture of black and yellow, because the yellow stones are new ones and the black ones are re-used from the old destroyed church. In stone decades, it will completely black again. Edit: some of course, but the autocorrect error is too fitting to correct.
