I have a stencil image of Karl Marx. The subject is mostly white on a black background. However, I would like to create another version of it where the subject is black on a white background. I thought that simply inverting the colors would do the trick, but it ends up looking terrible (see below) and not recognizable. This was puzzling.
Does anyone know how to do this correctly so the look is exactly the same and only the subject/background colors are flipped?
