I've just been looking at your colours, I think the Dulux Dieskau would work the best with the other colours you have to work with, choosing colours is such a personal thing and I know it can be really hard to choose and hope you make the correct choice. Oskuee is right, a paint job can look terrible half way through so you need to make sure you finish to get the proper look of colour. But the biggest thing to remember is it's only paint and it's the cheapest thing to change so if your not happy with the colour you choose you can always try something else. Happy redecorating :)

Dulux whisper white. Get a sample pot, paint a large piece of cardboard and see for yourself.

Yes they are meant to help keep the kitchen looking clean and tidy and also adding extra bench top when not not using the cook top, but I think if it fitted it would look better to have some tiling across the whole wall x

The flooring is such a big component of a space you really need to consider it as part of the whole look you’re aiming for. I would say that generally for practically the carpet would be darker than the walls.
