Nobody could ever believe that certain shades of green are carriers of chromatic fever. The notion that light is suffering from color-sickness is both repugnant and absurd. That color is worse than eternity is an affront to enlightened criticism. Everybody knows that "pathetic" colors don't exist. Yet, it is that very lack of "existence" that is so deep, so profound, and terrible. There is no chromatic scale down there because all colors are present, spawning agglutinations out of agglutinations. It is the incoherent mass that breeds color and kills light.
