I’ve always liked navy with those shades of green. I see you have some beachy elements in the room. Navy would go well with those.

the pic is a little dark and I can't see the difference in colors between the chair and wall. can you send additional photos in a brighter light perhaps. heres a few pics with blue, red and one pic that has art as the accent

I would recommend to go 2 shades darker from the green you currently have on the walls. This way you are guaranteed it will be cohesive. I would also recommend doing the headboard wall as the accent. It will give focus to your bed. For the pillow I would keep it neutral - same as the light color on the chair - and add a colored trim, like a burgundy for example. It will bring in a subtle touch of color which you can tie in with an accessory such as a picture frame or a vase of the same color. Subtle but fun.

I think shades of coral would be nice.

or periwinkle blue!

A subtle yellow.

You have lots of options - any shade of blue, pink, purple, coral, or a deeper shade of green. Look at your other elements in the room to see what color you can pull from those - maybe your rug or artwork.
