Can someone tell me how to create this effect?

If you take a look at the image I've attached. I'm trying to figure out how the red and blue "light beams" were created. I would like to use this technique for some other images I have and I cannot figure out how to create colored "light beams" like this.

Thanks

Paint opaque color beams on a new layer. Experiment with layer blending modes.

Sweeeet. I knew if I posted it here, someone would be able to make it simple for me.
