Sprite Grayscale Shader Filter Overlap
Hello there, I am tired of searching around and fideling with shaders, to no avail.
I really need help, I'm trying to create a shader that makes a given sprite turn all others behind it (on a lower "Order in Layer") become white and black.
Like this: 
Imagine the circle is one sprite, and the colors is another. when the circle goes above the colors, they go grayscale where both overlap.
