With a tile this tactile, restraint elsewhere can be a good thing. Natural timber, simple stone, warm whites and uncomplicated cabinetry give the surface enough space to stand out without competing for attention.
Aqua and Turquoise can take a bathroom towards a cooler, coastal or more natural palette, particularly alongside pale stone and timber. Sand brings more warmth, while White gives you the opportunity to introduce stronger colours elsewhere without the wall becoming visually heavy.
One of the more useful things to look for is contrast in texture rather than contrast in colour. Pairing a rippled wall with smooth cabinetry or a simple worktop can make both surfaces more noticeable. Adding several heavily textured finishes at once can have the opposite effect, as the eye has nowhere quiet to rest.
