Sorry but I can't post pics. What kind of stone would be good to use at an entryway?? I'm looking for something that would not need an added throw-carpet (door issues that cannot be changed) over the stone in wet weather. What colour tones would work with dark, mahagony coloured hardwood floors & walls that are painted BM Biscotti. I was thinking about a med. grey colour ie. not too light & not charcoal. Any other colour suggestions would be welcome.
