Contrasting colors that create a visually interesting effect are a trick you can always use when decorating a space. One way to apply this decor in the bathroom is to make colored grout. The grout in contrasting colors will distract from simple and boring tiles, but also will emphasize interesting ceramics, especially if tiles are with a different shape from the usual tiles. The particularly good look gives bright colors like the extremely popular yellow, pink, red, green, but also metallic colors that are trending. Of course, this is not just reserved for the bathroom, the grout in contrasting color will look nice in the kitchen and floors. This is one of those simple ideas that result in spectacular decor that will not go unnoticed.
