Recently, I asked a question about the plausibility of green superheated plasma (like the green plasma blasts in many video games) in real life. I actually found a post in the SciFi Stack Exchange asking a similar question about green plasma in Star Trek and noticed that one of the comments brought up Cherenkov radiation. After looking it up, I found that Cherenkov radiation is the blue glow around underwater nuclear generators caused by particles moving faster than the phase velocity of light in water.
My question is, can Cherenkov radiation be a different color than blue? Would the medium through which the particles are traversing, say air as opposed to water, have an effect on the color?
