Hi all!

I recently re-arranged our furniture and wound up a turquoise mid-century modern dresser in my master suite. I love the piece of furniture, but my current colors are peach/mauve/gray/tan, so I would like to get some new bedding and other pieces to freshen it up. The room is a very light gray, with wood trim. I would like to get away from my typical M.O. of being so matchy-matchy. The problem is, I'm having a hard time figuring out what kinds of colors to incorporate without being too matched and/or looking like a child's bedroom - I'd still like it to be nice and cozy!

Here are some pictures for reference --

Bedroom:

Dresser:

I don't have a photo of our bed, but it is this exact same bed frame (white) with a very similar slatted headboard in white:

The only pieces I'm really not able to part with are the bed and the dresser (and painting the dresser is out). We currently have these IKEA nightstands that have moved with us too many times and I'd love to replace with something with a drawer/storage.

We have these lamps:

And these curtains:

I would LOVE any advice for pieces for this room, including (but not limited to!): bedding (preferably including a duvet cover), art, decor, nightstands, lamps, and curtains.

Thank you in advance!
