Visual offset

1. The two oblique towers seem to be inclined on the right side, in fact two.

     When the body patterns are parallel, the vision may be offset.

2. The picture seems to be turning. In fact, it is still, because the composition is clever and the eyes are deceived.

3. The two-color quadrilateral overlaps, which seems to be obviously black and gray.

     But after the center line is covered, the upper and lower colors are the same.

4. The white block surrounded by yellow looks like a yellow block of yellow surrounded by black.

     In fact, the two whites are the same.

     Because the color of the surrounding color is easy to cause visual chromatic aberration.
