What colour paint with this wallpaper?

[justtryingtodomybest]

I really like this wallpaper and think it would make a great feature wall in my bedroom. Yes, yes I know - feature wall - but I like them!
Anyway, I like the charcoal version as I think it's a bit different and more grown up than the usual pink or blue options you get with toile de jouy.
But I'm not sure what colour paint to use for the other walls. The bedroom furniture is white so I think white paint would be too much - and, being in Scotland, it might be a bit cold. But would charcoal paint be too dark? I was thinking I could warm it up with lots of texture - a lovely throw, cushions etc.
Thoughts?

I think the 'Royal Heath' colour, bottom right of colour chart, would be perfect on the other walls.

Given the colour scheme of grey and white, you need a warm colour to make it a cosy room.

Step away from the gray.
I am in Scotland and have just repainted my utility room in a warmer colour because, although trendy, I did not appreciate the walls matching the skies.
