Changing color on highlight

Hi. So I’m using Tom Loomain’s method for outlining objects via a Post Process Effect. It’s working fantastically, but I’d like to, in certain circumstances, change the color an object is highlighted with. I couldn’t find a way to swap the texture on a Post Process Effect during runtime. My second thought was to create two PPEs, and turn off whichever one I didn’t want to use at the moment, but I can’t find a way to do that, either.

If anyone knows a solution (either a way to do one of the things I mentioned before, or an alternative way to change the color), I’d be very grateful.
