I would explore using a complimentary or split-complimentary color for accents. The compliment will be directly across the color you have on a color wheel. Split compliments would be the two colors to either side of this compliments. A less dramatic approach would be picking colors analgous to each other. These would be colors near what you have and next to them on the color wheel.
I use Color Impact 4 from Tiger Color in color consulting. It will let you play with color wheels and sehemes and it does beautiful blends from which you can pick colors. I think it is $50 for a license but you can try it for 30 days or something.
The major paint companies have virtual painting programs you might want to play with also. You upload your image (or find one in their image library close), mask the different areas to be painted, and play with colors to go in the areas.
Make sure you make color determinations based on how the room is to be used. Colors like you have will look very different under different color temperatures of light, especially if the color rendering index is low.
