Help needed picking kitchen wall tiles

[Timepasses]

We are re-tiling our (old) kitchen. Units are pale grey with oak worktops. Please help me pick wall tiles. I am tired of looking and need some inspiration. thank you

What colour are you looking for you?
At the moment we've decided on the brix range from tile mountain and the added bonus is they send a free samples

The colour is what I need help with. I am useless at putting things together

Bump anyone??
