The interaction of light and color is essential to the overall feel of a space. Consider that if there is no light, there is no color, no shape. The type of lighting - whether it is ambient, accent, or task - and the placement of that light directly affect how you see and perceive a space.
For some, the "do-it-yourself" lighting that is available at home improvement stores is sufficient for their needs. On the other hand, if you are the type of person who understands the role light plays and you want it to be an integral part of your home or the space you're designing, it's very likely you would benefit from working with a professional lighting designer. A professional lighting designer can provide you with a lighting system that minimizes glare; highlights and preserves your artwork; applies energy-efficient technologies; provides appropriate lighting for working in the kitchen, applying makeup or shaving in the bathroom, and working efficiently in other task areas.
