Disappearing Color Optical Illusion

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.

Stare at the center dot (for about 60 seconds from about 12 inches away) and shortly the various colors should blend into various shades of gray. Did this optical illusion work as well for you as it does for me? Let me know.
