Furniture in Fashion reports that bathroom mirror lighting fails for reasons of position and colour rendering rather than colour temperature, the setting households most often try to adjust. A fitting placed above a mirror throws shadow into the eye sockets and under the nose and chin, which is exactly where makeup and shaving take place, and no change in brightness or kelvin value corrects an absence of light.
