Ah, gotcha. Just keep in mind that it's easier to match/coordinate paint to bedding than vice-versa. My suggestion is to look into purples. Purple is the complement to yellow. Get some paint chips in blues, greens, reds, oranges, purples and see what kind of mix you like.

I think a light, soft grey would play up the golden detail on your curtains. Thinking something like Revere Pewter by BM. You could also go a grey/blue like Grey Owl by BM. Or paint three walls a neutral/warm white and an accent wall something bold like Urbane Bronze by BM. Good luck!

I think all beige shades will look good here except dark beige. A tree would also do just fine. I wish you good luck and if you are interested you can go to my website https://homebedideas.com where I talk in detail about the interior of the bedrooms.
