this may not be the right forum but I just did some new backsplash subway tiles in my kitchen. I noticed now that some of the tiles are almost gray instead of white. they came in sheets and all the boxes were sealed and the same color. it almost seems like they turned gray overnight. I used the same grout and wiped them all down but still have areas that are off color. anything I can do? thanks for any help
