Thanks for posting!! It sounds like your room has a lot of potential to be decorated in many different styles. It’s a blank (well, light orange) slate, if you will!
I don’t know if I would recommend green to be your accent color, judging off the orange-hued walls. Maybe a deep green or emerald/ teal tone if green is your favorite color! I would also recommend looking at muted pinks, wood and natural tones, metallics like silver and gold, or maybe going opposite on the color wheel with a blue tone!
I would also add curtains to your window, and wall art for sure! If you have the space for a mural, they are always a fun statement!
