Ever really think about grout color? I’ll tell you this, years ago I had a 16×16 tile with a dark brown grout and it looked amazing. It actually became the design feature of the room. I also had tile in my present home which I’m glad to say the tile is gone, was a 12×12 standard light tile with light grout. What a nightmare!!!!
IF and only IF I ever HAVE to have tile in my home again, dark grout is the way to go. I know it depends on the color of the tile but also considers the darker colors not just the neutrals.
