I’m doing an x-ray shader, I got this code, but for what I want it’s incomplete. Here’s the shader website:

My knowledge in shader is pretty basic, I’m studying weeks in Unity documentation and in various tutorials, but nothing comes close to what I need.
I need to make if one object is on top of the other the color turns green, in addition to having a density control of the material that makes it darker or lighter, and the same with the color intersected.
And to finish the possibility of putting a texture in black and white and have an individual control the internal with these same characteristics. If you can help me, thank you.
I tried via C # to change the color, but there remained a wagon hehehehhehehe.
This is what I have.

This is what I want to do.

I tried to use overlay, but it did not work. I needed to know how to get pixel rendering from the scene and compare with conditionals, or if someone has a better idea, merge or anything else will be welcome. Thank you.
