Evoking the colors of fall in a yellow toned room

What accent colors to decorate my living room? My walls are light yellow and my furniture is dark brown?

The best accents for a room like that would be orange, moss green, or deep red. You need something to give off a shot of color when you walk in the room. Light yellow and brown with orange is reminiscent of fall colors, so they can work together.

Colors that look like this http://houseofarearugs.com/Mystique-0020-Multi-p-544.html would be perfect in your room.

I'd avoid colors like blue, other shades of yellow, cream, or white.
