    I have probably said this before, but I can't get over the idea that someone could make a material that has completely different colors if you shine RGB light on it or if you shine true black-body white light on it.

    If somebody made this, where do I put my money? I want a shirt that is red outdoors and green indoors!

      In case it's unclear what I'm talking about, sunlight or a good old lightbulb has a light spectrum that looks like this:

      111111122221111111111111111

      But an LED light has a light spectrum that looks like this:

      000090000000090000000090000

      A flourescent light is not RGB, but it is also made of spikes rather than an even curve, the spikes are just just placed in other places. So you could have a shirt that has three different colors when you view it in white light, LED light and some common configuration of flourescent light.
