Those are very interesting results Thromm Arcadia! I'm going to give that a try too and see how it works out for me.

I tried it from a different angle and here are my results. I was initially trying to use a math_functions node but I wasn't able to get it to work properly so I switched to a color_math node and I have had some success with that.

My test scene comprises of a ball in the foreground, 2 cones in the middle of the scene, and a taurus with a cone in the center at the back of the scene. All of these are floating above a cloth plane which only has a gather node attached to the ambient channel and the ambient colour set to white.

All of the props have the same setup as you can see above with a color_math node plugged into the ambient colour channel. The node is set to add, value 1 is set to the colour I want the prop to be, and value 2 has a gather node connected to it.
