So you've picked your kitchen backsplash. Now what colour grout do you use? Design expert Karl Lohnes shares the answer.
Q: I've picked a white subway tile for my kitchen backsplash. How do I know what colour of grout to choose?

A: Matching grout to tiles—even those that are white—can be tricky. Although they might appear to be pure white, tiles often have either a warm or cool undertone. The simplest way to check is to place a tile sample on a blue background. If there's a cream or yellow undertone, you'll instantly see the warmth. Likewise, placing a sample on a yellow background will reveal any blue undertones. If your tile has a blue undertone, consider a cool white or grey grout. If the tile has a warm undertone, then choose a correspondingly creamy grout.
If your subway tiles are bigger than the standard three- by six-inch size, I suggest tinting your grout to create a pattern and to offset plain cabinetry and countertops. To determine the tint, take a cue from your appliances. A medium-grey grout works well for stainless-steel appliances, a dark grey for black appliances, and a pale grey for white appliances. If your countertops are heavily patterned, then match the grout to the tiles as you would with three- by six-inch subway tiles.
