This would work just like LCRY, but would change color according to it's temp like filter. It would only let that color photons through while making others bounce off. It would be able to allow us to make laser splitters that would seperate photon lasers into different colors allowing us to create different light shows of different colors that can be controlled with minimal effort. Description- PSCN turns on, NSCN turns off. Changes color according to temp, only lets that color photon through when charged. Catagory- Electronics.

I know that those can be used, but what about other colors?

But none of those let photons of a certain color through. only glass, clone, and lcry let photons through and they let all photons through.
