None of the colours featured in your two pics

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

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.

To be a voice of dissent, have you considered soft greens or green-grey? I've got Baltic Pine floors, pine cabinetry, stainless steel appliances, and black tiles in a BRIGHT west-facing kitchen. I went with Taubmans Swiss Meadow double strength and it compliments all the different elements. If you don't want something "obviously" green, check out Taubmans Alpine Snow (double) - it seems to change colour in different light. It's a pale green in full daylight, but looks soft grey at night.
