What colors work well with brown or beige sofa and carpet?

My room has brown carpet and brown / beige sofa. I would like used as a sage green or green curtain.Basically I would like to add somewhere. what other colors I can add or choose?

add sage brown refreshing touch of beige and neutral to add any color you like. something I suggest to my clients that may sound silly but works is to go through your closet, by pieces of different colors (one at a time) on the couch step back and take a good hard look its an easy way to see what colors you really like and go with well with your couch and carpet, once you've narrowed down to let each piece separately on the couch for a day to see if you like enough to live with it before you spend money, have fun with it
