This optical illusion relies on a principle called "Chromatic Adaptation".

An object may be viewed under various conditions. For example, it may be illuminated by the sunlight, the light of a fire, or a harsh electric light. In all of these situations, the visual system indicates that the object has the same color: an apple always appears red, whether viewed at night or during the day. This feature of the visual system is called chromatic adaptation.

Have you ever entered a movie theater on a sunny afternoon? The room probably appeared completely dark but as your visual system adjusted to the reduced level of light you were able to see better after a few moments.

This "adaptation mechanism" allows our eyes to recover from an oversensitivity to a particular stimuli. "Chromatic adaptation" occurs when our eyes adjust to certain color stimuli. Chromatic adaptation is one of the more easily fooled aspects of vision, and is prone to some of the most spectacular optical illusions.

  • if you pause it at 29-30 sec you will see it is colored at first even if you dont stare at all. Meaning it changes first to a color and then b/w.

  • Aside from the text at the beginning and the text at the end, there are only two images in this video. The chromatic one you see first and the black and white one you see second. If you are seeing anything otherwise, it is still a part of the illusion.

    In fact, if you pause it in the middle, and continually swap back and forth between the two images, you will still see the effect in action. "Staring" just makes it last longer.

  • That's interesting, the first time I watched it, it didn't happen. So I rewound the video, up to right before the change, and I briefly saw a coloration effect, but not enough to think of it as a color image. To be sure, I tried to pause it at the moment of transition, but wasn't able to. Then again, my mind is often resistant to optical illusions, it sorts them out very quickly.

  • Try it with one eye closed the whole time, making sure not to let your focus stray from the dot either before the change or during and after the change.

  • Fake... start the vid and stop the vid go to end and its 2 pictures

  • You're right. It's two pictures. That's not the trick.  The question is... is the second picture in color, or is the second picture in black and white?

see all

  • @996758444933 nop even if u look at the dot for 1 sec and turns to black and white ull see colours so thats why look at the corner until it changes to black and white ull see that there is no colours cuz it only shows colour when u keep looking at the middle even for 1 sec the more u look at the middle the more the colour can stay

  • @996758444933 nop even if u look at the dot for 1 sec and turns to black and white ull see colours so thats why look at the corner until it changes to black and white ull see that there is no colours cuz it only shows colour when u keep looking at the middle even for 1 sec the more u look at the middle the more the colour can stay

  • @996758444933 ur wrong cuz even if u look at the middle while it in colours and it will be black and white even if u look at the dot for 1 sec and then turns to black and white ull see colours look try not looking at the dot look at the corner and then wait till it becomes black and white ull see that it has no colours cuz u wasnt looking at the middle
