Can Warm/Cool Coexist in Living Room?

Trying to decide which direction to take our living room…we have more things on the warmer side but would like to head towards the cooler side.  Our rug is a more muted coral than the one shown here, but it has to stay in the room, as do the sofa and ottoman.  Everything else can be shuffled around the house.  We like the warm colors for autumn but would like something cooler for other times.  I really love the blue/jade/gold direction, but we have more things in the coral/orange direction.  We aren’t really a fan of the high contrast blue and orange combo but are looking for either a very versatile plan or something that is a happy medium between hot hot hot and cold because this room is our main (and only) sitting/TV watching/game playing/book reading/exercising space (and we spend a lot of time here). Thoughts?
