Grout
Choosing Grout
The right color grout can make a huge difference in how the tile will look.
Match
If you're looking for a less pronounced grout line, select a grout color that "matches" your tile selection. Selecting a grout color that is one shade either lighter or darker helps tie everything together. This is also an advisable choice when your tile has only one color because it helps create a fluid look. This can also be the best option when using more expensive tiles, such as marble tiles or granite tiles.
Contrast
If you're looking to make the tile stand out, select a contrasting grout color to your tile. This frames each tile and draws attention to them. You will also want to look at using a thicker grout in this instance to really highlight your tile selection. This is a good choice for more decorative tile patterns.
Neutral
If you're looking for what some feel is the safest choice, select a "neutral" grout color from the tans, beiges, or grays. If you want something that will have mass appeal, a neutral matching color is the most widely recommended approach.
Other Grout Considerations
The selection of your grout color is important to achieve your desired look; however, you still need to consider the type of grout being used. Grout functions to bond tiles and stone edges together and prevent chipping so it is important you or your tile contractor understand the types of grout available.
You should also consider traffic patterns in the room where your tile and grout will be used when selecting a color. A very light grout is probably not a good idea for a busy kitchen, but could be ideal for a less used guest bath. Note: A darker grout will fade quicker, while a lighter color will show stains and dirt.
