What colour tiles? Kitchen

[FrameyMcFrame]

Help needed! We are having grey painted kitchen units with solid oak work tops. What colour tiles would go with this combination? I was thinking teal or blue metro tiles, or bright yellow but not sure if yellow would go with the wood? Don't really want to go white as I'd like a splash of colour...

Thanks, that's reassuring. Yes, I'm thinking turquoise and blue.

I would go for dark blue tiles on the Walls like the colour of the middle lamp you added.

We have a grey howdens kitchen with oak worktops and I went for cream metro tiles as I was worried a colour would date. We have added colour with a purple rangemaster cooker and purple accessories. I love it 3 years later
