Burgundy, navy and forest green work beautifully together...one of my favorites for home decorating as well as clothing and quilts! Gold, cream, beige, warm tan make nice light accents.
Go to the paint chip section at WalMart or Home Depot and find the strips with graded shades of each color and that will help you if you are wanting to go from dark to light within a single color. And of course you can play around with the various colors to see which ones you like together, then take them to the fabric store and look for fabrics that are similar shades.
Good luck & have fun!
