What colors are in the rest of the house? I can see a coral throw and amber lamps, but no idea what other color or pattern is present. Need more to go on.

BM lily White

BM Beacon Gray

will give a very subtle Barely blue tone...gorgeous with your rust and amber accents!

I would consider switching out the mustard lamps for silver ones since mustard can be more challenging to pair with taupe (the headboard). I then think a wallpaper with a cream background and taupe and silver in the pattern could be elegant.
