Because of the importance of illumination and colors and their vital effect in developing interior space and controlling the psychological and physiological comfort of the space user, this paper has been prepared to explore the role of utilizing light and colors in interior design of Living Rooms (in Cairo-Egypt) in order to support and develop the design process aiming to provide psychological, environmental and visual comfort inside the space.

A descriptive analytical approach is implemented through a thorough study of colors and lighting and their effective relationship within the space of living room.
