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 :)

It was one of the colours the Dulux rep recommended. If you can, get sample pots and try them out. Best way to check your colours as photos don't always give a true reflection of the colour. Then you can have a look against your tiles and in different light.

I would let your natural elements shine ..match your wall colour to your classic white laminate and be lazy and paint the same for the ceilings so not to distract from your features or you could use your Caesar stone Urban as an inspiration and choose that colour as wall colour..ie go a bit lighter ..since you can play around with the colours as your room has lots of natural light .. Urban is a nice colour..brownish grey.. personally I'd just go white..

Thanks everyone. Nik Star I did get some colour swatches for navy, but then didn't have the courage to go ahead. Think I will have to just be content with some navy towels.
