I need advice on decorating using deep green walls with brown rugs. ?

I am very happy with my color scheme. Everything is earthy and my light beige tan couches and oak tables and light garnet chair and terra cotta fireplace tiles and door tiles look great. I don't know what accents i should get for pillows and table clothes. Deep red is a great accent in here. What other color accents? I have chandeliers and bronze sconce lights with crystal. I have white sheers and a couple trees. What kind of accent peices would look good on the tables
