None of the colours featured in your two pics

We do need a photo. What colour is the roof?

Hi there! I do love your kitchen and I don't want to put a complete spanner into the works… but I'm not in love with the timber finishes. I can see the timber door frame adjacent to white sliding doors and then the timber capping piece along the top of the cupboards adjacent to the ceiling. However, do I see a stainless steel finish to the kick board below the sink area? To me, the wood is a difficult distraction from your new kitchen and I would like to see it painted over …I can't see the adjoining areas and I understand you have a brick internal wall…. but it seems to ruin the look to me and might be hindering you finding the right combinations of white and make the space seem more limited than it is by creating a border.

You can borrow wallpaper books from suppliers and compare some you like by holding the samples up to your walls. Be sure to test how well they complement each other at different times of the day under different light conditions. I know it's hard to know for absolute certain how a particular wallpaper pattern will look on a large scale, but it's a place to start. And the people at the decorator stores will be happy to advise you.
