I think the white trim gives it a much more contemporary look. It's more work to have it done in a different color, but the overall look is cleaner.

I would go with a gold or yellow ... of course I happen to love teal/ turquoise and gold/ yellow together. Something in variations on the photos below... maybe some pink accents if you have a girl or lime green or blue accents if you have a boy.

I'd like to suggest that the most important thing here is more about who is using the room. If It's a child's bedroom use lovely children's curtains - there's so much around and any pattern could pick up the wall and floor colours. If a guest room and not used often I'd suggest a beautiful velvet or good quality Linen and forbid the little ones from going in to that room!!!!!! alternately a blind attached at floor level could be raised or lowered so the view is still there but with privacy from waist height perhaps. Good luck. Bee

Textured linen or with a subtle print wont date. Feature walls make a room smaller as they jump out ar you. Wouldnt recommend. Get some interesting art or craft. Pick up colour with accesories
