Blue black white gold dress. The secret of the "mysterious" dress: why people see it white and gold or blue and black. "This kind of handicraft is being reborn." Clothes in wet and dry felting techniques were presented at the Sherstival fashion show in Grodno
It all started with the fact that Scottish singer Caitlin McNeill, under the nickname Swiked, posted an ordinary photo of the dress on Tumblr. In the signature, the girl explained that she and her friends cannot understand what color it is:
- People, help! Is this dress white and gold or blue and black? My friends and I cannot agree. And it drives us crazy!
And after a few hours, millions of people were divided into two camps: some claimed that the outfit was blue and black (#blacknblue), and others that it was white and gold (#goldandwhite). The color of the dress even had its own hashtag #TheDress, which topped the top trends in the world.
But even after the girl confirmed that it was indeed blue with black stripes, the online debate did not stop.
Even the stars argued on Twitter:
Kim Kardashian:
What color is this dress? I see white and gold, and Kanye saw blue and black. So what color is it ?!
Taylor Swift:
I don't understand this debate about the color of the dress. I'm scared already. PS: it's blue and black!
What do the #goldandwhite team think?
Looking at the picture, people who thought the dress was white and gold, most likely paid attention to the background. Taking the bright backlight for sunlight, they decided that the dress is in the shade, which means that its light areas should change tone towards a bluish tint.
What do the #blacknblue team think?
“Blue-blacks”, on the contrary, look at the light areas of the dress out of context and clearly state that they are bluish or blue, while instead of “golden” fragments in the picture, they see black ones, keeping in mind the effect when, due to bright light, under at a certain angle, black becomes rusty brown or even golden.
Thus, an amazing construction is obtained in which one conflicting side defends its direct observations, and the other - predictions.
Experts explain that such a different perception is due to the structure of each person's eye, as well as the calibration of the monitor on which he looks at this dress, and the lighting of the room in which he is. At the same time, experts unanimously say that such a discrepancy in colors is extremely rare.
This is physics. In other words, in the case of photography, people mistake the light in the background for sunlight and conclude that the dress is in the shade, which means that its light areas should become bluish. So, there is no pure white color, but our brain thinks out for us the whiteness of the snow or dress.
Others ignore the light in the background and see a blue dress. They call the gold fragments black, because they remember that if you look at a black object in the bright sun, you can see gold.
Ophthalmologists in their own way explained the reason for what was happening:
Your retina is made up of “rods” and “cones” that convert light stimuli into nervous excitement. They convert the signal in different ways. "Sticks" are more sensitive to light, see shadows, and work more efficiently in the dark. The "cones" are sensitive to color, but less sensitive to light. That is, in low light conditions, you see more "rods" than "cones".
The dress appears blue / black or white / gold depending on whether your eye has more rods or cones and the light conditions in the room. (This is made possible by the different colors that blend around you.) Different people have different remnants of "rods" and "cones" - those with color blindness are the first to suffer.
But the rods are also very sensitive to light. The rods detect color using a pigment called rhodopsin, which is very sensitive to low light, but is emitted and destroyed at higher light levels. And it should take about 45 minutes to readjust (well, how does your eyes take time to adjust to the night, in other words). Basically, if you look at a dress in bright light and see one color, then if you leave for half an hour in a dark room and return, the dress may well change color.

Scotland News. The photo of this dress literally blew up the Internet. Thousands of people around the world argue about the color of the dress in the photo posted on the social network.
The photo was posted a day ago by Scottish singer Kathleen McNeill.
Kathleen McNeill, singer:
Two of my close friends are going to get married. And the bride's mother sent her a photo of this dress. When the bride showed the dress to the groom, they argued over its color.
And it started. The snapshot, along with the hashtag #TheDress, topped the top trends on American Twitter. The stars of the first magnitude argue about the color of the dress. Jimmy Fallon, Julianne Moore, Kim Kardashian see the dress in white and gold, and Taylor Swift, James Franco, Kanye West - in black and blue.
Taylor Swift, singer:
I don’t understand why this strange dress gets so much attention, and I feel a trick here. I am scared and confused.P.S. It is blue and black.
Julianne Moore, actress:
Guys, what's wrong with you! It is white and blue. It is obvious!
In reality, the dress is blue and black. After the international community started a dispute about the color of the product, it was swept off the shelves of online stores in a matter of hours.
Why does everyone see the dress differently, ophthalmologists tried to explain. The dress appears in blue and black or white and gold, depending on the lighting conditions in the room.
In addition, a person is able to distinguish colors thanks to visual receptors, namely, special cone cells that process the incoming signal, process it into an impulse and send it further along the optic nerve to the brain.
Jay Neitz, a neurophysiologist at the University of Washington:
Our visual system is accustomed to sweeping aside information about the source of light and scooping up information about truly reflected light. I have been studying the individual characteristics of color vision for 30 years and in this case I see the greatest differences in individual perceptions of all that I have seen.
Ophthalmologists assure: a different perception of the color of a dress does not mean that you have problems with your eyes or, God forbid, with your psyche.
There is a scientific explanation for why people see different colors in the same picture. This is an optical illusion. Objects reflect light at different wavelengths or in different colors, and the human brain determines color from the reflected light. Surrounding objects can also reflect color and affect perception. In this photo, there are many other colors around and they are mixed, and the brain cannot immediately determine the color of the dress.
If, say, a person looks at a dress in bright light, then leaves for half an hour in a dark room and returns, then most likely the color of the dress will change for him.
However, if you increase the brightness of the screen of a smartphone or monitor, you can see how the dress changes color from white-gold to blue-black.
Optical illusion is used creatively by artists. For example, drawings created using the “anamarphosis” technique look like meaningless or surreal abstractions. But it is worth putting a shiny metal cylinder in a certain place - and the picture, reflected in it, takes on clear realistic outlines. See for yourself. Photo by I.

"This kind of handicraft is being reborn." Clothes in wet and dry felting techniques were presented at the Sherstival fashion show in Grodno
News of Belarus. About the warmest fashion show. The festival of wool and felting "Sherstival" was organized for the residents of Grodno, the News program "24 Hours" was reported on STV.
Fashion show in elegant hats, coats with views of Paris and exclusive dresses with a fashionable combination of wool, lace, silk and chiffon. Four collections for real ladies were created by local craftswomen. Each item is a real exclusive, because it is made in a single copy.
The products are made using the techniques of dry and wet felting - just like our ancestors did. This type of handicraft is traditional for Belarus. And, as you can see, it is still popular.
Vera Belaya, a resident of Grodno:
I was, of course, very impressed by this. There was a girl walking, and her houses were below. I think, "My God, the whole city is coming." It's so interesting.
Elena Rozhenkevich, wool felting master:
It is very pleasant to work with wool, you forget everything. Sometimes the husband asks: "Are you going to sleep soon?" I say, "Yes, yes." And then I looked - and it was already daylight on the street.
Marina Chikun, head of the Heritage Center for Folk Crafts:
Felting properties were invented 8 thousand years ago. Maybe it has gone somewhere, but now this type of handicraft is being revived.
Neurologists were asked to explain the phenomenon of different perception of the color of a black and blue dress, which users of social networks have been discussing over the past day.
As a reminder, yesterday a Tumblr user under the nickname Swiked in his toumblog a photo of the dress and asked for help in determining its color. According to Swiked, she and her friends cannot agree on one opinion: some see the dress in black and blue, others - in white and gold. University of Washington neurologist Jay Neitz, who sees the dress in white and gold, says it's the largest individual difference in color perception in 35 years of his practice.
The eye perceives color through reflected light waves, explains Wired. The light hits the retina, the pigments of which process information and send it to the brain. Pigments perceive different colors depending on the wavelength of the received light. In this case, the first flash of light that hits the retina can have any wavelength (that is, a different color). After the retina receives the light reflected from the object, the brain tries to "subtract" the subsequent information from the data of the first flash.
Since people are active during the daytime, they most often perceive daylight. It can range from pinkish red to blue-white and reddish. "This will happen if the visual system sees an object and tries to ignore the chromatic shift of daylight," says Bevil Conway, a neurologist at Wellesley College. "Thus, people will ignore either bluish and see a white and gold dress, or yellowish and see a black and blue dress." He is probably referring to the current lighting around the person.
Knights and Vice have two theories. First, differences in perception may be related to age. According to him, over time, the retina of the human eye changes and begins to perceive less blue color. That might explain why Knights, 61, sees a white and gold dress, while his student sees a black and blue one. However, this theory does not explain the differences in people of the same age.
The second assumption is about color consistency. and colored lighting. Constant lighting means that a person will see red in both bright and dim lighting. But with colored light, the brain makes a correction. “If I walk into a room and turn on the red lighting, the white objects will reflect the red color. And if I have some kind of red thing with me, it will also reflect red. " When processing this information, the publication explains, the brain can decide that a red object is actually white, even if it saw it as red under normal lighting.
“I saw this with my red Volkswagen,” the scientist adds. - I got into the car when it was dark enough outside, and someone in front of me turned on the brake lights. Then my car was only lit by brake lights - and it looked white! " A Vice reporter tried to translate this theory into a photograph of the dress and assumed it was taken under bluish lighting. Therefore, the brain, perceiving colored light, thinks that the dress is actually white.
Wired asked for in-house designer work with photography and decompose individual areas in the RGB palette. The blue areas did turn out to be blue, but the designer attributed this to the larger area of blue in the photo. At the same time, some of the dark areas in the image had a palette (R 93, G 76, B 50) close to orange. The specialist attributed this to the fact that we see this place on a white background and perceive it as black. If you cut it out and look at a black background, then the section R 93, G 76, B 50 may seem almost orange.
Knights, who saw the dress in white and gold, says the same: “I printed the picture, then cut out a piece and looked at it out of context. The color turned out to be somewhere halfway between gold and blue, but not dark blue. It's just that my brain thinks that blue is in the light source, and the brain of other people thinks that blue is in the dress. " Conway adds: “Most people will see blue on a white background as blue. But some may see blue on a black background as white. "
Jay Knights ended the conversation with Vice with a promise to devote the rest of his life to this phenomenon. “I thought I was going to treat blindness, but now I’m going to do it,” he said.
Do you believe in what you see? Especially for you - pictures that deceive the eyes and the brain.
What color is this dress?
This dress (by the way, what color is it?) Blew up the Internet and in a matter of hours divided the world into two camps. For those who have spent the last few days in a coma, here's a quick summary of what happened. The author of the photo posted it on Tumblr with the question "What color is this dress?" However, it was not possible to get a unanimous answer: some see in this photo a blue dress with black lace inserts, brightly illuminated by electric warm light, others argue that the dress is white, the inserts are golden, and the dress itself is in the shade.
The dress became a meme in the shortest possible time and has already bored everyone endlessly. Ultimately, however, this illusion is just a demonstration of one of the many ways to trick imperfect human vision. We have collected 16 more optical illusions that will make you disbelieve your eyes.
