After you have finished your new black and white bathroom tiles and the bathroom as a whole, it is time to add a few contrasting notes. Although you can leave the two colours as they are, and the bathroom will still look as edgy and elegant as you intended, adding a pop of colour can elevate the whole look of the room and bring a designer vibe to your bathroom. The most popular colours to mix with black and white to achieve an expensive look are soft pink, gold, teal and green. If you aim for a luxurious look, selecting gold and teal or some shades of pink will help you reach that goal. If you plan to accentuate your black and white bathroom to look more natural and zen, green and lighter brown will appear more earthy and clean.
