Cool Video: Mysterious Pink

In this Cool Video, MinutePhysics explains why there is no pink light. They do it in a highly entertaining fashion in a little more than 60 seconds.  Yet, as other scientists argue, all our colors are a sensations of the brain.  Color is not a function of light or reflections of light, but it is our brains making sense of the some of the different wave lengths of light.
