Whats the best color grout to use?
Usually MEDIUM GRAY. Here’s why: The purpose of grout in visual terms is to make each tile distinct like a gray pencil line in a watercolor. A medium or “natural” gray provides just enough contrast to most colors, unless you have gray tile, and then you might want to consider black or a dark gray. Avoid pure white unless you are trying to make something that looks like a little kid’s summer camp project. Most building material stores such as Lowes and Home Depot cary about 30+ colors of grout. Bring a few of each color of your tiles with you, and you can pick the color grout that works best with all the tile.
