It is interesting that so much response has occured in regard to lights. Some of the responses are very well thought and contain much information. As far as what everyone said about the color red I wonder why red is popular because red is the first color in the sprectrum to dissipate under any stress. Meaning that if you placed many different colored lights in water and sank them red would be the first color to disappear. I would imagine the same to be true if in total darkness all of these same lights were set on something and when walking away from the lights red would be the first color you would lose sight of. So what makes red so effective close up?
