Lighting significantly influences interior design by altering the perception of color and space, which can profoundly affect the overall ambiance of a room. The quality, direction, and intensity of light can change how colors appear, making them look warmer or cooler, brighter or darker. For instance, a warm light source can enhance warm tones in a space, while cool light can highlight cooler colors.

Additionally, appropriate lighting can create an illusion of space, making a small room appear larger or a large room feel more intimate, depending on how it is utilized. For example, strategically placed task lighting can illuminate specific areas, drawing attention to certain design elements, whereas ambient lighting creates a more general illumination that sets the mood for the entire space.

While some might think lighting is primarily functional or relegated to natural sources during the day, interior designers recognize the versatile role it plays in enhancing aesthetics as well as functionality in both residential and commercial environments. This multifaceted approach to lighting is essential for successful interior design.
