Green is a neutral color because it goes with almost every single color.
I would take one of your cushions to the store to see what colors you are attracted to that match your furniture. It could be as simple as an awesome set of decorative pillows (Pier One Import, Home Goods, Marshalls, TJ Max), a throw blanket or a set of fabric curtains which define other colors you can use in the room or on the walls.
In colors of today are oranges, turquoise, yellow and purple.
Try a pastel or sherbet orange and browns.. earth tones? My walls are sherbet orange and we have beige sofas with touches of green, brownish gold on the pillows and curtains and coffee table covers
green goes well with most earthy, natural colors. try light browns and light yellows. maybe a little bit of gold like small accents here and there!
