Color illusion. Color illusions that deceive our brain (18 photos)
Optical Illusion - Illusion Pictures with Explanations
Do not take optical illusions seriously, trying to understand and solve them, it's just how our vision works. This is how the human brain processes visible light reflected images.
Unusual shapes and combinations of these pictures make it possible to achieve a deceptive perception, as a result of which it seems that the object is moving, changing color, or an additional picture appears.
All images are accompanied by explanations: how and how much you need to look at the picture in order to see something that is not really there.
For starters, one of the most talked about illusions on the web is the 12 black dots. The trick is that you can't see them at the same time. The scientific explanation for this phenomenon was discovered by the German physiologist Ludimar Herman in 1870. The human eye stops seeing the whole picture due to lateral inhibition in the retina.
These figures are moving at the same speed, but our vision tells us otherwise. In the first gif, four figures move at the same time until they are adjacent to each other. After separation, the illusion arises that they move along black and white stripes independently of each other. After the disappearance of the zebra in the second picture, you can make sure that the movement of the yellow and blue rectangles is synchronized.
Carefully look at the black dot in the center of the photo while the timer counts down 15 seconds, after which the black and white image will turn into color, that is, the grass is green, the sky is blue, and so on. But if you do not stare at this point (to cheer yourself up), then the picture will remain black and white.
Without looking away, look at the cross and you will see how a green spot will run along the purple circles, and then they will completely disappear.
If you look at the green dot for a long time, the yellow dots will disappear.
Stare at the black dot and the gray bar will suddenly turn blue.
If you cut a chocolate bar 5 by 5 and rearrange all the pieces in the order shown, then an extra piece of chocolate will appear. Do this trick with a regular chocolate bar and it will never run out. (Joke).
From the same series.
Count the players. Now wait 10 seconds. Oops! Parts of the picture are still the same, but one football player has disappeared somewhere!
The alternation of black and white squares in the four circles creates the illusion of a spiral.
If you look in the middle of this animated picture, then you will go down the corridor faster, if you look to the right or left, then more slowly.
On a white background, the gray stripe looks uniform, but as soon as the white background changes, the gray stripe immediately takes on many shades.
With a slight movement of the hand, the rotating square turns into randomly moving lines.
Animation is obtained by overlaying a black grid on the drawing. Before our eyes, static objects begin to move. Even the cat reacts to this movement.
If you look at the cross in the center of the picture, then peripheral vision will turn the starry faces of Hollywood actors into freaks.
Two pictures of the Leaning Tower of Pisa. At first glance it looks like the tower on the right is leaning more than the one on the left, but the two pictures are actually the same. The reason lies in the fact that the human visual system considers two images as part of a single scene. Therefore, it seems to us that both photographs are not symmetrical.
In which direction does the subway train go?
This is how a simple change in color can make the picture come to life.
We look exactly 30 seconds without blinking, then we look at someone's face, object or another picture.
Warm-up for the eyes ... or for the brain. After rearranging the parts of the triangle, suddenly, there is free space.
The answer is simple: in fact, the figure is not a triangle, the "hypotenuse" of the lower triangle is a broken line. This can be determined by the cells.
At first glance, it seems that all the lines are curved, but in fact they are parallel. The illusion was discovered by R. Gregory in the Wall Cafe (Wall) in Bristol. Therefore, this paradox is called "The wall in the cafe."
Stare at the middle of the picture for thirty seconds, then move your gaze to the ceiling or white wall and blink. Who did you see?
An optical effect that gives the viewer a false impression of how the chair is standing. The illusion is due to the original design of the chair.
English NO (NO) turns into YES (YES) using curved letters.
Each of these circles rotates counterclockwise, but if you fix your eyes on one of them, it will seem that the second circle rotates clockwise.
3D drawing on asphalt
In which direction does the ferris wheel rotate? If you look to the left, then clockwise, if you look to the left, then counterclockwise. Perhaps you will have the opposite.
It's hard to believe, but the squares in the center are motionless.
Both cigarettes are actually the same size. Just place two cigarette rulers on top and bottom of the monitor. The lines will be parallel.
Similar illusion. Of course, these spheres are the same!
The droplets sway and “float”, although in reality they remain in their places, and only the columns in the background move.
Our vision is very easily able to deceive our brain with simple color illusions that surround us everywhere. Some of these illusions are waiting for you further.
How many flowers are in the picture?
The blue and green spirals are actually the same color - green. Blue is not here.
The brown square in the center of the top face and the "orange" square in the center of the front face 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.
Does the bottom of the figure seem lighter? Use your finger to cover the horizontal border between the top and bottom of the shape.
See the chessboard with black and white cells? The gray halves of the black and white cells are the same shade. Gray color is perceived either as black or as white.
The figures of horses have the same color.
How many colors are there besides white? 3? four? In fact, only two - pink and green.
What color are the squares here? Only green and pink.
Optical illusion
We look at the dot, and the gray strip 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 a dot in the center of a black and white image for 15 seconds, the picture takes on colors.
Stare at the center of the black dot for 15 seconds. The image will become colored.
Look at the 4 dots in the center of the picture for 30 seconds, then move your gaze to the ceiling and blink. What did you see?
At the intersections of all the white stripes, with the exception of the intersection where you are fixing your eyes at the moment, small black spots are visible, which are not really there.
disappearance
If you look closely at the dot in the center for a few seconds, the gray background will disappear.
Focus on the center of the picture. After a while, the blurry color images will disappear and turn into a solid white background.
Optical illusion refers to such effects of visual perception that occur involuntarily or consciously in a person observing certain images.
Such effects are also called optical illusions - errors of visual perception, the cause of which is the inaccuracy or inadequacy of the processes occurring during the unconscious correction of visual images. In addition, the physiological characteristics of the organs of vision and the psychological aspects of visual perception also take part in the process of the emergence of optical illusions.
Optical illusion, presented in this section of the site, is to distort perception by incorrectly estimating the length of segments, the size of the angles, the colors of the visible object, etc. Its most popular types are depth perception illusions, flips, stereo pairs and motion illusions.
Illusions of depth perception include inadequate reflection of the depicted object. The most famous examples of such illusions are two-dimensional contour pictures - when they are observed, they are unconsciously perceived by the brain as one-convex. In addition, distortions in the perception of depth can lead to incorrect estimation of geometric dimensions (in some cases, the error reaches 25%).
Optical illusion The flipper consists in the image of such a picture, the perception of which depends on the direction of view.
Stereopairs make it possible to observe a stereoscopic image by superimposing them on periodic structures. Focusing the eye behind the picture leads to the observation of a stereoscopic effect.
Moving illusions are periodic images, a long look at which leads to a visual perception of movement from separate parts.
See the frog and the horse in this optical illusion?
This picture is very famous. Flip it over to see how men see women after 6 bottles of beer.
Mysterious face found on Mars. This is a real photograph of the surface of Mars taken by Viking 1 in 1976.
Stare at the four black dots in the center of the image for about 30-60 seconds. Then quickly close your eyes and turn to something bright (a lamp or a window). You should see a white circle with an image inside.

There should be 11 faces in this picture. The average layman sees 4-6, attentive - 8-10. The best see all 11, the schizophrenics and paranoids 12 or more. And you? (Don't take this quiz too seriously, I've heard there might be 13 faces.)
Can you see the face in this pile of coffee beans? Don't rush, it's really there.
Do you see squares or rectangles? In fact, there are only straight lines in different directions, but our brain perceives them in a completely different way!
Optical illusions are nothing more than an optical illusion of our brain. After all, when we look at a picture, our eye sees one thing, and the brain at the same time begins to protest and argue that this is not at all the same. So it turns out that our mind creates illusions, which begins to analyze the color, the position of the light source, the location of edges or corners, etc. Due to this, visual images are corrected.
Be careful! Some illusions can cause tearing, headache, and disorientation in space.
Invisible chair. The optical effect, which gives the viewer a false impression of the location of the seat, is due to the original design of the chair, invented by the French studio Ibride.
Volumetric Rubik's Cube. The drawing looks so realistic that there is no doubt that this is a real item. Twisting a sheet of paper, it becomes obvious that this is just a deliberately distorted image.
This is not an animated gif. This is an ordinary picture, all elements of which are absolutely motionless. It is your perception that is playing with you. Hold your gaze for a few seconds at one point, and the picture will stop moving.
Look at the cross in the center. Peripheral vision turns beautiful faces into monsters.
Flying cube. What looks like a real cube floating in the air is actually a drawing on a stick.
Eye? Shot from photographer Liamm, who was filming a foam shell, but soon realized that it was an eye looking at him.
In which direction is the wheel spinning?
Hypnosis. Stare without blinking at the middle of the image for 20 seconds, and then look at someone's face or just a wall.
Four circles. Be careful! This optical illusion can cause a headache lasting up to two hours.
Ordering squares. The four white lines seem to move randomly. But it is worth imposing images of squares on them, as everything becomes quite natural.
The birth of animation. Animated images, superimposing a grid of black parallel lines on the finished drawing. Before our eyes, static objects begin to move.
A selection of optical illusions and two-valued pictures.
The eyes are a complex mechanism that helps a person to correctly perceive the world around him. But as practice shows, even such a perfect, at first glance, mechanism can be easily deceived.
This can be done with the help of color contrasts, dramatically changing proportions and all sorts of small details. Thanks to all this, the human eye will see an optical illusion that changes depending on the angle at which you look at it.
What is visual illusion, optical illusion, surrealism?
Optical illusion
Optical illusion (visual illusion)- this is an incorrect perception of the eyes of certain pictures or surrounding objects. In this case, the eyes see the image a little differently than the brain tells them. The correct background, depth and geometric shapes, arranged in a certain sequence, help to achieve a similar effect in the picture.
All these little tricks prevent the eyes from properly scanning the image in front of them, and as a result, the brain makes a person see a distorted picture. Surrealist artists use this feature of the human eye with might and main and try to surprise people with paintings that have a special meaning. That is why surrealism can also be attributed to optical illusions that can provoke a person to vivid emotions.
Pictures-illusions for the eyes, optical illusion, and their secrets
Illusion pictures for the eyes
As you probably already understood, illusion pictures cause our brain to perceive images not quite the way they look. This happens because the brain also has patterns, and if it understands that the eyes do not perceive the picture quite correctly, then it starts sending impulses that make it completely different.
Also, the brain can be deceived with a bright color. If the same picture is superimposed on a different background, then its individual details will be perceived by the eyes in a different color.
People are even more misled by pictures that depict geometric shapes that contrast in color. At first glance, it may seem to a person that they are located parallel to each other. But in fact, if you take a closer look at them, you can understand that they are looking in opposite directions.
And, of course, do not forget that loving the picture from different angles looks different. In view of this, if you make it contrast, then you will see different depths in it. This can be seen in the contrast cube example.
Complex 3D stereo images for eye training with explanations
Stereo image for better vision
3D stereo image
3D picture
3D stereo images- this is nothing but the same optical illusions, simply created by the alternation of dots and textures. The main principle of such pictures is based on the ability of the brain to compare different data and estimate the distances to objects, figures and points as accurately as possible.
Such images are very often used to train the eyes in the treatment of ophthalmic pathologies. According to experts, if a person looks at such pictures for at least a few minutes a day, then his eyes will relax properly.
In order to correctly see the stereo image, you will first need to move away from it at arm's length and try to completely relax your eyes. You should try to look through the image, as it were. If you do everything right, then after a while you will see the most realistic three-dimensional picture.
Black and white illusion pictures, optical illusion with explanations
Volumetric picture in black and white
Black and white flats
If you carefully read our article, you probably understood that illusion pictures work best on color contrast. That is why black and white images are the easiest to deceive our eyes. If you just look at the simplest picture, designed in this color scheme, you will notice that your eyes jump from one element to another, not knowing where to stop.
That is why, when looking at such an optical illusion, it seems to a person that the figures in the image are constantly moving, floating and moving. If, for example, a portrait of a person is depicted in such a color scheme, then, depending on the color, he will change both his outline and his shape.
Moving pictures optical illusion with explanation: photo with explanations
Eyes see movement due to the right color scheme
Moving pictures are good because they create the effect of realism. When a person looks at them, it seems to him that he really sees a waterfall or a sea that is swaying. The most pleasant thing in this case is that a person does not need to take absolutely no action to see everything correctly. As a rule, at the first glance at such a visual deception, the eyes immediately pick up the movement of some individual details.
geometric moving picture
If it is a geometric picture, then it will be created using contrasting shades and identical geometric shapes. In this case, the eyes will perceive it almost the same as a black and white image, due to which it will seem to a person that the drawing is in motion all the time.
Gifs - optical illusion
The square can only be seen when turning
The picture shows how you can visually enlarge the subject.
GIFs, like any other illusion pictures, deceive the human eye and it does not perceive them quite the way it did originally. In this case, everything is built on movement. It is from how fast and in which direction the elements move that a person can see different images.
GIFs also make it possible to visually reduce large objects and enlarge very small ones quite well. This happens due to the approach or distance from the object that you will look at.
Illusion pictures of hypnosis vision: photo with explanations
Optical illusion with depth effect
Picture-hypnosis concentrating attention on the central point
hypnosis pictures- these are images that are able to introduce a person into a state of light trance, which helps to relax the nervous system. Most often, this effect is achieved with the same contrast and the same type of lines or figures, placed from largest to smallest. Looking at the image, a person tries to understand the secret of the continuous movement of objects in his field of vision.
And the more he tries to unravel the riddle of the picture-hypnosis, the more he sinks into a kind of trance. If you try to look at the center of such an optical illusion for a long time, then it will inevitably begin to seem to you that you are moving along some kind of corridor or simply descending somewhere. This state will lead to the fact that you relax and for a while forget about everyday problems and obstacles.
Double pictures of the illusion of vision: photo with explanations
The double meaning of minimalism
Mirror optical illusion
The main secret of double optical illusions is the almost complete repetition of all, even the smallest lines. This creates a mirror effect that allows you to create an image that looks different from different angles. In this case, you can combine two completely different patterns in the picture, the main thing is that they ideally fit each other in shape and color.
Also, a double picture can consist of two completely different images, just when you look at it, you will see the outlines of the same figure.
Pictures for optical illusion for children: photo with explanations
Pictures for optical illusion for children
In principle, optical illusion pictures for children are also based on the contrast of colors, the depth of lines and the right background. Just unlike images for adults, in this case, reverse drawings are most often used.
Looking at them, the baby tries to recognize what his eyes actually see, thereby contributing to the development of logical thinking. And in order to make it easier for little children to perceive what they see, as a rule, the drawings depict animals or plants that are familiar to them.
For example, it could be a drawing that shows a cat that turns into an angry dog when turned over.
In addition, children perceive pictures very well, in which the same object has a different length. In this case, the illusion effect is achieved by the correct background and different colors of two figures that are completely identical in shape.
Pictures for optical illusion geometric, triangles with explanations
geometric illusion
geometric illusions- this is nothing more than an image of objects of various shapes, which the eye perceives not quite the way it is customary in geometry. In this case, the ability of the human eye to determine the color, direction and size of objects is used.
But if in geometry they are arranged according to certain rules, then in this case, for example, a rectangle can be composed of several triangles of different sizes. Such an illusion is designed for the fact that a person, instead of seeing triangles, will consider parallel lines and try to understand how similar they are.
Also in geometric illusions, contrast in size is very often used. Looking at such an image, a person does not see that the two central circles are the same size. Even when looking closely, he thinks that the circle surrounded by smaller objects is larger than the one surrounded by large ones.
Pictures for optical illusion with a dress: photo with explanations
Pictures for optical illusion with a dress
If you spend a lot of time on the Internet, then you have probably already come across a picture with a question about the color of the dress. As a rule, people cannot give an unambiguous answer to this question, as at different times of the day they see a different shade of clothing. What is it connected with? As mentioned at the very beginning of our article, the human eye is a rather complex mechanism, the main one in which is the retina (responsible for the correct perception of color).
The retina itself consists of rods and cones, the number of which determines how brightly a person perceives a particular color. For this reason, the dress may seem pale blue to some people, while saturated blue to others. When it comes to optical illusion, lighting plays a huge role here. In daylight, it will appear lighter, and in artificial light, it will appear much brighter and darker.
Picture for optical illusion - "Girl or old woman": photo with explanations
Picture for optical illusion - "Girl or old woman"
Each of us at least once in our lives has identified the optical illusion "Girl or old woman." But, having seen it, we simply forget about it and do not even think about why our eyes see such a dual picture. In fact, in this case, two completely different images are skillfully connected in one drawing.
If you pay closer attention, you will realize that one drawing flows smoothly into another. For example, the oval of a young girl's face is also the nose of an old woman, and her ear is the eye of an old woman.
Tattoo surrealism on optical illusion: photo, explanation

Tattoo with volumetric effect
As you probably already understood, an optical illusion is nothing more than a correctly drawn picture. Therefore, if you wish, you can easily make yourself a tattoo in the style of surrealism.
All you have to do is apply it using contrasting colors, correct directions and background. All this will help you create voluminous and even visually moving images on your skin. You can see an example of a surrealist tattoo a little higher.
Optical illusions of perception in the interior: photo with explanations
Mirror surfaces in the interior
Optical illusions are good because with their help you can radically change any room. Mirrored surfaces are considered the simplest visual trick. With their help, even the smallest room will seem huge and bright.
horizontal lines on the walls
Different textures change the space well. If you want to easily stretch the room, then decorate the walls with horizontal lines. If you need, on the contrary, to reduce something, then frame it with vertical lines.
Soaring table in the interior
If you wish, you can decorate your kitchen with the so-called floating furniture. To do this, you will only need to buy a table, the legs of which will be made of either transparent plastic or glass.
hidden doors
Also, if you wish, you can decorate your house with an invisible door. To achieve this effect, you will have to install a door with hidden hinges, and then decorate it in the same color as the walls.
Optical illusion: dress code
Optical illusion: color
As you probably already understood, visual deception can help a person make the world around him more organic, and this applies not only to the interior. If you need to correct the figure, then you can try to do it with the help of optical illusions. All that will be required of you is to choose the right color and shape of your outfits.
Surrealism in painting: photos, paintings, explanations
Surrealism in painting
Two-faced picture
Optical illusions are very popular with artists. They help them to make the pictures deeper and more interesting not only in visual perception, but also in meaning. As a rule, for this they use the so-called two-faced pictures.
Most often, in this way, they try to disguise a caricature drawing. Surrealist artists use a similar technique to create drawings with a triple image, thereby trying to give their masterpiece a deeper meaning. You can see examples of such paintings a little higher.
Paintings in the style of surrealism by Salvador Dali
Tenderness and strength in one picture
Salvador Dali is considered the most famous surrealist in the world. He always painted in his paintings, images that made a person far from art think. Perhaps that is why even now people look at his masterpieces with great pleasure and try to understand what the great artist was thinking when he painted them.
