You can go with almost any color...lt blue, tan, soft yellow, green..... Whatever you like looking at best.

I agree, there are a lot of colors you could use, depending also on what other colors you have in other room(s) near the mudroom. I have terra cotta tile in my mud room and front hall, and in the mud room I have Stonehouse and in front hall I have Everlasting. Both BM colors.
