Looking for help with grout color. My bathroom tile, floor and wall, is French vanilla marble. The marble contains taupe and some hint of pink, but dominant shade is vanilla. What color grout would you recommend? Salesperson at tile shop advised to purchase white standard grout (TEC), but I am having second thoughts. I am concerned this may be too light and will get dirty. All else seems to be a bit off. Shades of vanilla by other brands are too yellow. Any suggestions? Thank you.
