This comparison of warm and cool also enables the lighting designer to shift the balance of the warm and cool lanterns in accordance of what time of day it is. For example, if a scene was set in the middle of the day, the warm and cool lanterns would be equally bright, so the shadows created would be filled equally by warm and cool light, giving the actor's face a balanced look similar to that of standing outside in the middle of the day. However, as it becomes later in the day, the cool lantern would become brighter than the warm lantern, so the light upon the actors face becomes cooler overall, suggesting to the audience that the time has shifted into the evening, without any mention of time in the scene itself.
