Hello everyone

I would like know how I could change the sprite color only in the area where is occur a collision between two objects, in the intersection of the colliders, per pixel, for exemple: I have two blue 2D objects with circle colliders, when they colide, I want change color to red in the intersection of the collision, where the restant part of the images continue blue.
Could somebody help me in this question?
