I just painted living room BM Edgecomb Gray and purchased new gray houndstooth fabric sofa, black leather chairs, and glass metal tables. Need help with accent colors and how to decorate rest of space. Room is narrow but long and doesn't get a lot of light (no overheads) so lamps are critical. Any suggestions for rugs, large round mirrors for over FP, lamps, windows, pillows? I'm partial to blue accents but am open to others! Help - I need some direction :-). All other furniture/ items in room are temporary and will go (bookcase, lamps). Thanks!
