If you go with the black bed, get a rustic and in fall colors night stand, that will stand up with the orange. Or that particular bedspread has golds, browns, and other shades... you might even be able to work a fall leaf red (sort of a dark faded red) in there for the night stand and the red into more accent pillows that would take the Halloween away. Stay away from bright limey greens and not picking up more of the orange or black and you could make it work well.

A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.

I would say blackcurrant as an accent but I love purple :) the lime green I feel may go out of trend quicker. Many thanks Jade

We need a bit more info are the wall colors staying, all the art on the T.V wall needs to be gone the 2 floor lamps really do not work together I have no idea what that turquoise thing is on the right maybe a curtain , with waht you show IMO you could go any direction for fabric for the chairs I think they might be fun in zebra print the black and cream one with black foot stools
