We are rather fond of tiles and more and more brands are adding to their existing ranges with fun, patterned and textured options. They are easy to clean (good for us) and can completely change a space. By adding a patterned tiled floor or wall, you can keep the rest of your scheme very simple.
American brand Fireclay‘s slim Scalenes and versatile Right Triangles (available in 3”, 4” and 6” sizes) can be applied in a wide range of patterns— create diagonals, stripes, squares, pinwheels, chevrons and more.
It may take a little more time and work to actually get those little shapes up onto the wall, but they look perfect when done. We would see this neutral mint and green as a splash-back in a simple, toned-down kitchen.
