Inverse color when light hits the surface.

 Well, question is how i can affect material color when lightning hits it? For example I have blue colored surfae and i need it to be redish where PBR light hits its surface. Who knows how i can achive that? And i dont want manually affect light color, it should be as it is from enviroment.

Hey, this is something that should be feasible with the specular/glossiness workflow. If not, this is something you would control directly within a custom shader.
