What colours will complement this wallpaper?

[DwpAnxt]

here
There is white painted panelling around most of the room and neutral carpet .The furniture (wardrobe etc)is oak coloured .The bed head is still pine but can be painted.

I need help .Left to myself I will just get everything in matching colours

Just wanted to add (and shamelessly bump) that I already bought bedding in the same blue

chocolate brown would go very nicely

If you look at all the pictures, you can take your cues from those - choc, as mentioned above, plus warm creamy biscuity, and maybe gold. It looks like the bedside table in the pic is mossy greenish? If you have the bedding already, lay some colours that you like on it and see what works. Nice paper btw.
