This is an optical illusion application.
A black-and-white picture looks like a color picture.
This is sample pictures which I made with this application.

Please continue looking at the guide point near the center.
When it is displayed by the application corresponding to the GIF animation, the picture is switched.

When the black-and-white picture does not look a color picture, please try the following.
- Do not move position of your eyes and the screen.
- Continue looking at the guide point after switching to a black-and-white picture.
