A very popular topic on the Internet is optical illusion. You've probably already seen many, but let's once again be surprised at how our vision deceives us.
We are surrounded from birth by an illusion, the so-called additional reality created by our brain. It is so familiar to us that we do not notice it at all. This is an illusion of color. For example, a rainbow. We do not look at the rainbow, we ourselves "create" it. What we see is actually connected with the peculiarities of human vision - for other living beings that do not have a similar eye structure, the rainbow does not exist at all.
Look at some evidence of how easy it is to fool our eyes.
How many colors are in the picture?
The blue and green spirals are actually the same color - green. There is no blue color here.

The brown square in the center of the top edge and "orange" in the center of the front edge are the same color.
Look closely at the board. What color are cells "A" and "B"? It seems that "A" is black and "B" is white? The correct answer is below.
Cells "B" and "A" are the same color. Gray.
You can load the first picture into a graphics editor and compare the color of the cells yourself.
Does the bottom of the figure appear to be lighter? Close the horizontal border between the top and bottom of the shape with your finger.
See a chessboard with black and white squares? The gray halves of black and white cells are of the same shade. Gray is perceived as black or white.
The horse figures are of the same color.
How many shades are there, apart from white? 3? 4? In fact, there are only two - pink and green.
What color are the squares here? Only green and pink.
We look at the point, and the gray stripe on the orange background becomes … blue.
In place of the disappearing purple spots, a green spot appears, moving in a circle. But it doesn't exist in reality! And if you concentrate on the cross, then the purple spots disappear.
If you stare at the point in the center of a black and white image for 15 seconds, then the picture takes on colors.
Look at the center at the black dot for 15 seconds. The image will turn in color.
1) Relax and watch without stopping for 10 sec. 4 small dots in the center.
2) Then slowly move your gaze to the wall (or something large and monochrome) near you.
3) You will see how a light circle is formed.
4) Blink a couple of times, and you will see how a figure is formed in this circle. Blink more … the figure will be clearer …
5) Does it work?
At the intersections of all white stripes, except for the intersection where you are currently fixing your gaze, small black spots are visible, which in fact are not.
If you stare at the center point for a few seconds, the gray background will disappear.
Concentrate on the center of the picture. After a while, the blurry color images will disappear and turn into a solid white background.
LOOK AT THE CROSS!
Artist Kaia Nao. Participant of the competition "Illusion of the Year 2012". A completely static image of a star appears to be rotating.
Well, I'll show you one more on the same topic …
The illusion was created by amateur photographer Robert Bruce Murray III. The inscription confidently flows over the observer.
If you place purple and white dragees correctly on the chessboard, you can distort the illusory perception, although all the lines on the board are absolutely straight.
But what if you remove all the dragees? See:
But I liked these. The animation is obtained by overlaying the drawing with a black grid. Before our eyes, static objects begin to move.
That is, it all depends on which side to look at.
