Colorful light aspect

I am currently working on a cyberpunk type of world and it is really hard to bring up that colorful night light that fills the city and really gives it that colorful gleam. I found copper and some other materials to be good for building and the glow squids for some additional highlight but it would be helpful to have a different colored light source with of course a variety of light. Maybe like glow stone but in different colors (I’m not good with ideas).
