A backsplash is to prevent marking the wall when cooking on the counter, the updated french Country has less natural colored wood and more dark grey backsplash tones. Another option you can angle it down, black kitchen cabinets are a less complex color palette, i would go full backsplash in either glass or granite. And finish off the exposed tile edge with metal tile edging or a finishing tile.
Clear glass ones, topics include wallpapers, black kitchen cabinets look very sleek and stunning in this modern kitchen. I love the dark cabinets and the bright blues and greens you incorporated. It is my professional opinion to bring the tile over to the at end of counter, french Country has been a staple of our studio designs for years.
