Projector color

I'm wanting to use projectors under each of my characters in the scene (10). For your team I want the color to be green and for the opponent team red. Since I couldn't figure out how to change the color in code I thought I'd just drag 2 light projectors as children to each character and disable them both. Then I'd set the Main Color in the editor for 1 of them to green and the other red. Well this doesn't work because I assume they are both using the LightProjector material and setting the Main Color for that sets it for all instances so they all end up being the same color.

What are my options here to get the result I'm after?
