I ran across an illusion that purported that if you stared at the center the colors in the image will be represented by shades of gray. The best I could do with that illusion was shades of red. I decided that it missed the mark, but I recalled the Disappearing Fluff optical illusion that did cause colors to vanish into a gray mist. Using the color scheme from that illusion I modified the original image (developed by Ed Minchau) until I succeeded in creating an optical illusion where the colors faded away and all that was left were shades of gray.
