Speaking in terms of home furnishings, lighting is absolutely key. The wrong sort of lighting can throw off the look for an entire room. The different types of floor lamps should be explored in order to perfectly accentuate the colors and accents within the room of a home. More modern rooms will call for cleaner, brighter lighting, while amber tints and softer glows are popular in rustic themed rooms.
When you first get started on home interior decorating, it is a good idea to have at least some notion of the kind of color scheme you might like. That is not to say that you cant change your mind while you are working out a plan. It is much better to change at this stage than when you already have the paint on the walls.
