While it may not seem directly linked to the lighting aspect, the presence of the impluvium and its associated architectural features contributed significantly to enhancing light in these interiors. The compluvium allowed natural light to enter the atrium, thus illuminating the space. The shiny surface of the water in the impluvium also reflects light, further enhancing the brightness of the room. This interplay of light through these architectural elements offered a beautifully lit environment that was both functional and aesthetically pleasing. In contrast, options such as fresh paint on walls, large windows, and open floor plans do not pertain to Roman architecture specifically. While all of these elements can improve lighting in various contexts, they are not defining features of Roman design that specifically aided in the illumination of indoor spaces. Roman architecture is particularly noted for the use of courtyards and atria that incorporate openings to the sky, allowing for the effective harnessing of natural
