We're with Valduff. Shades of purple and plum can really add depth to a chic scheme like yours. Particularly with your gorgeous counter top. Grey is also a good call, as it will coordinate with your kitchen units but allow room to add coloured accessories. It can depend on the light quality in your room- we always recommend grabbing some tester opts in a range of shades. Paint your walls or A4 sheets, and see what the colours look like as the light changes throughout the day.

Glass - Tiles look busy, the grout is a problem as well - picking up dirt easily, and discolouring takes place over time. Glass is easy to clean, and in terms of colour, I could recommend to go for something timeless like a neutral colour. Bold will provide you with the initial wow factor, however a timeless neutral colour is dfficult to beat when your chosen bold colour isn't trendy anymore .:)
