Nowadays sky is the limit for kitchen cabinet colors and countertop colors. In order to have clean look and contemporary kitchen. Kitchen backsplash color is very important. Generally speaking "contrast creating" in between the surfaces is such an important way to go. For instance If you have white shaker cabinet and dark color countertop, Greek Thassos White Marble would be great selection for backsplash. Thassos White Marble is a plain white marble like almost snow white color. 1x4 Herringbone design or hexagon designs are the trendy designs.
if you have gray cabinets and light color counter top also Italian Calacatta marble mosaic tiles and Italian Bianco Carrara Marble mosaic tiles would be great options. Gray veins on the mosaic tile and white background will help to create contrast extremely well. Carrara White Marble Tiles background color is little darker Calacatta Marble mosaic Tile and Field tiles.
