Question About Lights

My question is.....How do you make multi colored Lights in FSDS? Im working on a ship for CFS2 that has deck lights and Im looking to add green and maybe red lights to the stern of the ship to make night approaches easier. I have tried several of light tags to see if any of them produce a different color then white but I did'nt find any that worked. So if any of you guys have any idea on how to do this I would appreciate the help.
