Living room window treatments help wanted!?

ok so i want to redo my window treatments. i will do my best to describe all my furniture so you can help me decide on colors and such. so first of we have a light tan couch suede fabric, matching recliner, and i got a chocolate brown chaise lounger also suede. carpeting is a light beige/tan color, slightly lighter than the couch and walls are snow white. we have 3 windows in the room, 2 behind couch and 1 on adjacent wall. the room is kind of small. no other furniture besides tv and stand. we live in military housing so i cannot do anything too drastic and unfortunately i cannot paint the walls. after our last move we got rid of end tables and coffee table because of lack of space, we also have 2 small children and a dog. any helpful ideas are greatly appreciated. as of now we have chocolate brown and mossy green throw pillows and blankets. willing to change that of course, little too camo for my tastes, lol. thank you again to anyone who responds.
