Creating a new spotter perk with a different color.

[Giveth]

What I'm trying to do is as the title says, create a new spotter perk with different shader effects so that I can apply it to an armor with a script. I've got all of that figured out, its just changing the color of the spotter effect that I can't figure out. The red shader for when Boone spots a target is there. I found that easy enough, but it isn't referenced by anything- which leads me to believe that maybe its hardcoded?

I don't want to change the color of Boones effect, I want to make a new one in a different color, is this possible?
