Welcome to Homearama 2016: Guest Bathroom, our next stop on the tour of the fabulous Southern Belle. When the homeowners mentioned that they wanted to incorporate grays into this space, I knew I would pair it with yellow. Yellow + Gray Yellow is not one of my favorite colors, but yellow and gray is one of my favorite color combinations. Our plan was to paint the vanity gray and the walls yellow and use timeless elements to finish the space.
