In our living room our couch is a dark moss color, the curtains and end tables are black, the carpet is white and there is a light brown trim in the room.
What color/s do you think I should paint the living room?

I t sounds like you now have too many colors in your living room and you look for a way to make them all blend well. I'd paint the trim in the same color as the couch and give the walls a very pale green color, Same color as the couch, just much paler, almost white. I think this will blend everything nicely together.
