there are loads of nice colours out there! Popular at the moment are reds, teal, lime green and purples. I would pick whichever of those you like best and pick up some things - a couple of cushions or vases or a change of curtains might give you some inspiration.
Here's a couple of ideas to show you the colours in a mainly brownish scheme:
