Here's a very simplified version of what it could look like. One red light, one blue, and they're about of equal strength/brightness. The same principle will apply whether it's a light prop or an emissive surface. The first pic is set to "Dome and Scene" Lights in the render settings, so the white dome light is washing out some of the effect of the colored lighting. The 2nd pic shows the lighting effect when it is set to "Scene Only" so it's just those 2 (red/blue) lighting sources illuminating her. The outfit is normally a light gold/white color, so you can see here the effect each light has on the suit/target. Also if the lights are literally just casting into each other's paths and not aimed in a sort of opposite manner, the produced effect will be a pinkish/purple lighting color as they mesh together on the target.
You can play with the luminance settings of the lighting, if you're using an emissive surface like in your case (under surface settings-"emission" for the surface that carries the emissive area) until you achieve the desired amount of light/color. When you say you're practicing with emissions I'm assuming you mean you already know how to set a surface to be emissive and adjust it's settings so I won't go into further detail on that. I hope this is what you're question is about...not sure if there was something more you wanted to know about it.
Also btw if you wanted to see some examples of surfaces being turned into emissive lighting, I do that kind of stuff quite a bit in my renders...here’s a few showing blue/red emission in my images…not exactly in the way that you described perhaps but just so you can get an idea of some possibilities. You can check out more in my gallery if you want to see more:

Yes this helps.
Thank you!
