Help me pick a color!!

Okay guys. We are getting a new couch. Its this charcoal one with the ottoman. Only our ottoman is going to be charcoal as well. The top picture is my current living room. I’m replacing the couch. It’s not the prettiest couch but it’s down feathers and SOOO comfy 😩 As you see, the walls are white and everything is pretty neutral. This dark couch is going to really change things up. What color should I paint? And what color curtains would go well?
