Consider three-dimensional or textured tiles to emphasize your tiles while maintaining a monochromatic color scheme.

The high contrast makes the grout and tile the main focus of the room and might make smaller spaces seem a bit busy.

Light gray has a soft, pleasant feel that can make a room seem fresh and bright. Choose a light gray with warm undertones (yellow, red, brown) for bright and warm decor, or one with cool undertones (blue, purple) for darker, cooler decor.

Darker grays appear cooler than light grays and work great with room colors like blues, purples, whites, and greens.

Brown works great in high-traffic areas like hallways or bathrooms since it’s easier to maintain than white or black. [6] X Research source

Green is a fun color to use because there’s a shade of green for just about any room or circumstance. The possibilities are endless!

Super bright, fire truck reds will help light up the room and make the space feel more playful.

Blue is a popular color in room decor, so blue grout can help tie a room together in a subtle way if you have blue artwork, furniture, or other decorations.

Try spacing your tiles slightly further apart to let this unique color pop. Warm orange grout is rarely overwhelming unless it clashes with the room’s decor.

Bright colors and neons can get overwhelming fast, so use thin strips of grout between simple-shaped tiles like squares or rectangular subway tiles.

Match metallic grout to the gold, copper, silver, or brass fixtures in the room for a refined, modern aesthetic. [14] X Research source Metallic grout doesn’t pop as much as glitter or colored grout, so use it in rooms with muted colors where it won’t have to compete for visual attention. Glitter and metal grout can reflect some light onto your white tiles to add more color, dimension, and visual interest to the room.

If the room seems too simple or you need a specific color to tie together various pieces, consider a grout that’s darker and boldly colored to make a statement. Grouts with cool undertones (blue, purple) look “icy” compared to warm-colored decor, while warm undertones (red, brown) look redder compared to cool decor.

Black grout is more likely to fade or look dirty than other dark shades and usually needs more upkeep.

Matching grout and tile can also help small spaces look bigger or more open. Highly contrasting grout works best if the dominant colors in your decor are black and white, or if you need to add a specific color to tie a room together.

Contrasting grout with closely-spaced tiles will still show, but won’t take center focus in the design of the room like thicker grout lines will. There’s no standard spacing for tiles according to the Tile Council of North America (TCNA). The width depends on your preference and the cut of the tiles.
