Choosing a Room Color
I recently learned that at Home Depot I can get a small can of sample paint for about $2.50. Well worth the money considering I could be stuck with a gallon of ugly paint.

Painters and decorators suggest you buy a small amount of the colors you're considering. Your paint store should be able to mix them in any brand and any color. Once it's on the wall, it will be easy to determine if it needs to be lighter or darker or if it's completely wrong.

Take them home and paint a 2' x 2' area on the wall. If you're concerned about testing the colors on your wall, you can paint some sample boards that can be easily moved around to see how they'll look with the furniture, floors and other items in the room.
