them to convey emotion more effectively than before. 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. To be totally realistic in this representation of daylight, four lanterns should be used to cover one area of the stage, in two pairs at 45 degree angles, so on each side of the actor's face both a warm and a cool light would be present. This would enable the lighting designer at midday to switch the warm light from one side of the actors face to the other, simulating the sun passing overhead in real life, enhancing the realism. Alternatively, this effect can be achieved with two lanterns equipped with scrollers (a device which fits on the end of the lantern capable of holding different colour gels and switching them during the performance) each containing a warm and a cool gel. However, scrollers are renowned for breaking unexpectedly in the middle of shows, and are also very noisy in operation, making them often unsuitable in a quiet venue, and therefore in a best case scenario two lanterns from each side should be used. Having said this, smaller theatres with fewer resources use this method to great success with only two lanterns per area of the stage. A third method, developed before scrollers, was to use three instruments, two on one side and one on the other. Three gel colors were used. The colors in the two lanterns on the one side were picked to be relatively warm and cool in relation to the single color on the other side. For instance colors of pink, blue, and lavender might be chosen. Pink is warmer than lavender and blue is
