Interior design is distinguished by light and shade. Proper lighting is important. Light changes the mood of a room just as it does the perceived size of a room. Placement and type are important aspects of interior design, and they work in conjunction with color selections, room size, availability of natural light and furniture selection. The elements that come together when the right lighting is achieved transform a room into a seamless combination of functionality and style. The use of lighting can add to or subtract from the overall colors of a room or from only those surfaces the light is meant to enhance.
Darker colors make a room feel smaller and cramped, while light-colored walls do the opposite. The illusion of space is defined by light reflected off of the surfaces of the walls. Some types of lighting help with this illusion by further illuminating the walls.
In addition, directional lighting, such as a track light, can soften the wall colors. There is also recessed can lighting, which has a soft, downward glow that illuminates the floors, not walls. This is opposed to lights hung from the center of the room, which provide ambient illumination, or wall lighting. In both cases, this can affect how light or dark a colored section can appear.
