Been thinking

After a recent trip in a sightseeing submarine. Colors change significantly as you go down in the ocean. Which brings me to my next thought in this process. Are we only focusing on the light that is being produced by whatever phenomena/orbs/NHI are ? Has anyone tried to do any kind of analysis to the color of these lights? There must be some sort of wavelength that they are giving off. Light is nothing more than a wavelength, correct? Maybe I’ll make this more simple. When fireworks are a certain color, they are burning a certain substance Such as copper for blue, sodium for yellow, strontium for red. Has any of our citizen scientist done a spectral analysis? What about any other kind of wavelength? Whether the wavelength be sound, an electrical pulse, possibly a nuclear pulse. OK, a heartbeat if you will???
