Scottish singer Caitlin McNeill posted a photo of the dress on Tumblr asking: What color is the dress? White and gold or black and blue?

People's opinions are divided: some believe that the color of the dress is blue and black, others - white and gold.

Celebrities added fuel to the fire :) So Taylor Swift tweeted that the dress is blue and black:

I don't understand this odd dress debate and I feel like it's a trick somehow. I "m confused and scared. PS it" s OBVIOUSLY BLUE AND BLACK

Kim Kardashian (Kim Kardashian) and Kanye West (Kanye West) consider: white with gold and black with blue, respectively:

What color is that dress? I see white & gold. Kanye sees black & blue, who is color blind?

Photographer Hope Taylor(Hope Taylor) helped sort this out with Adobe Lightroom.

If you make the color of the image "warm", then the dress looks like white and gold, if the color is "cold", then the dress will turn blue and black:

Considering the lighting conditions in which the original photograph was taken, the color debate has a clear answer: dress color blue and black.

The phenomenon of different color perception is interesting. There are versions that this may be due to a number of factors, including the person's age, lighting, background color, etc.

And here is how this dress looks in the store:

The Amazon online store also confirmed the black blue color dresses:

The excitement around this dress was so great that the LEGO company decided to reconcile the parties: choose the color you like best :)

P.S. In the photo of Caitlin McNeil, I see white and gold. Light blue/pale blue and gold to be exact :)

Human eyes and brains have evolved to distinguish colors in a world illuminated by the sun. Light enters the eye through the lens different lengths report different colors. Light hits the retina at the back of the eye, where pigments activate neural connections in the visual cortex, the part of the brain that translates signals into images.

The brain figures out what color light is reflected from the object that the eyes see, and separates this color from the color it considers "real". "Our visual system is supposed to throw out information about lighting and extract information about the color that is actually reflected," Naitz said. “But I’ve been studying individual differences in color perception for 30 years, and these differences in dress color perception are the most noticeable I’ve ever seen,” the neuroscientist added (Naitz herself sees white and gold in the photo).

Usually the color perception system works without failures. Humanity has evolved to see in daylight, however light can change colors. The color of sunlight changes from pinkish-red at dawn and blue-white at noon to red at dusk. "Your visual system is paying attention to these color changes and trying to ignore some of the day's color shifts," said Wellesley College neurologist Bevil Conway. “Thus, people either do not perceive blue, and then they see white and gold, or, conversely, gold, and then they look at a blue and black dress,” the scientist concluded (he sees blue and orange in the photograph).

In other words, explains TJournal, in the case of photography, people take 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, however, our brain thinks out for us the whiteness of the snow or the dress.

Others do not take into account the light in the background and see blue dress. They call gold fragments black, because they remember that if you look at a black object in the bright sun, you can see gold. In addition, it is likely that some of the blue-seeing people knew in advance about the real color of the dress, and because of this, the brain gave the correct answer. If you take a sample of the colors from the dress in Photoshop, you will find that the colors of the dress are bluish and greenish brown.

Swiked posted a photo of the dress on February 25, asking what color it was. According to her, she argued about it with friends. She added that the dress was actually blue. Internet users quickly began to argue about this topic, and the hashtag #thedress topped the top Twitter trends in the US. Kim Kardashian (white and gold), singer Kanye West (blue and black), singer Taylor Swift (blue and black) and David Duchovny (greenish blue) joined the discussion. The Sony Play Station account in Australia also managed to joke about this topic: “Introducing the new white and gold Dualshok 4 controller.” The manufacturer of the dress has already stated that so far only blue variant, but soon white and gold will also be on sale.

The dress, the picture of which was posted on the Internet, divided the planet into two irreconcilable camps.

A photo of a strange dress (pictured in the middle), posted on the eve of the BuzzFeed portal, literally blew up the Internet. “Guys help me, is this dress white and gold or blue and black? My friends and I can't agree and we're going crazy,” wrote one girl, after which millions of users around the world went crazy.

Look at the image and determine: is the dress in the middle white and gold or blue and black?

Few people could imagine that a simple picture can divide Internet users into two irreconcilable camps. Some vehemently claim that they clearly see a dark blue dress with black stripes of lace, others a white dress with gold lace.

It's really all about biology. The difference in perception is explained by how the human eye and brain have evolved to perceive the world illuminated by light. Light that enters the human eye hits the retina, which consists of two types of photoreceptors - cones and rods, which are taught in school. The rods are more sensitive to light, and are more responsible for perceiving the shape rather than the color of objects. Cones, on the contrary, are more responsible for the perception of color, rather than the degree of illumination of the object. In other words, at dusk we perceive the world more with rods than with cones.

The color scheme in which various objects are perceived depends on what is more in the retina of a particular person - rods or cones, and on what kind of light the object is illuminated.

Rods perceive light intensity due to the visual pigment rhodopsin, which is very sensitive to low-intensity light and is destroyed when exposed to bright light. At the same time, it takes about 45 minutes to restore it - which is why a person needs time to get used to twilight lighting normally.

For the same reason, if a person looks at a dress in bright light, then goes into a dark room for half an hour and returns, then most likely the color of the dress will change for him.

“Our visual system is used to rejecting information about the light source and scooping information about the actual reflected light. I study individual characteristics color vision for 30 years, and in this case, I see the largest differences in individual perceptions of all that I have seen, ”says Jay Neitz, a neuroscientist at the University of Washington.

What's more, color perception is affected by how our brain tries to adjust colors and light levels to figure out what color an object really is. Just as modern cameras adjust light balance, the human brain does this automatically.

But at the same time different people either ignore the blue hues, perceiving the image as white and gold, or ignore the yellow hues, seeing a blue and black dress.

Many other optical illusions are of a similar nature, including the famous example of black and white checkerboard cells.

Real dress colors

And here's what the dress actually looks like.

The actual color of the dress is in line with the minority opinion - the posted photo shows that it is actually blue-black.

What dress did you see?

Explanation

How they see white-gold

Looking at the picture, people who thought the dress was white and gold most likely paid attention to the background. Taking 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 (for example, due to the same sky).

Something like this in this picture, most will see a white dress, although this is not so

How blue-blacks see

Blue-blacks, on the other hand, look at the light areas of the dress out of context and clearly state that they are bluish or blue, while instead of the “golden” fragments in the picture, they see black, keeping in mind the effect when due to bright light under at a certain angle, black becomes rusty brown or even golden.

A photo of a dress that a girl from Scotland posted on the Internet divided the whole world into two camps - some see it dress in blue and black, other - in white and gold. Who is right and who is deceived by his sight?

The controversy over the color of the dress erupted after Scottish resident Caitlin MacNeil posted a picture of the dress on her blog and asked the question to Internet users: “Help me, is this dress white and gold or blue and black? Me and my friends can't agree and we're going crazy." Within a couple of hours, the photo of the dress was scattered all over the Internet, and the world was divided into two camps: some began to claim that the dress was blue and black, others were sure that it was white and gold.

What color do you think the dress is in the photo?

It should be noted that there are much more people who see the white-gold color (according to numerous surveys on the Internet). In fact, the dress is blue and black - this was confirmed by its owner Caitlin. However, this fact did not close the debate about color.

Why do some people see the dress as blue and others as white?

When asked why someone sees blue-black, and someone sees white-golden colors in the photo of the dress, scientists tried to answer. The human retina consists of two types of photoreceptors - cones and rods. The rods are more sensitive to light and are responsible for perceiving the shape rather than the color of objects. Cones, on the contrary, are responsible for the perception of color, and not for the degree of illumination of the object. In other words, in the dark we perceive the world with rods rather than cones.

Yes, susceptibility colors depends on what is more in the human retina - cones or rods, as well as on how the object is illuminated. “Our visual system is used to rejecting information about the light source and scooping information about the actual reflected light. I have been studying individual color vision for 30 years and in this case I see the greatest differences in individual perceptions of all that I have seen, ”says Jay Neitz, a neuroscientist from Washington.

And what color do you see the dress - black and blue or white and gold? We are waiting for your comments and do not forget to press the buttons and

Thousands of people around the world are arguing about the color of a dress posted by a user on the Tumblr social network. His photo was posted a day ago by Scottish singer Kathleen McNeil.

“Two of my close friends were going to get married. And the mother of the bride sent her a photo of this dress. When the bride showed the dress to the groom, they argued over its color,” McNeil explained the reason for the appearance of the dress in her account. And asked for advice from users to figure it out.

And thus “broke” the Internet, writes the site www.kp.by. Some say that the dress is black with blue, others see white with gold. Even the stars of show business have become involved in this strange game.

“I don’t understand why this strange dress gets so much attention, and I feel like there’s some kind of trick here. I'm scared and confused. P.S. It is blue and black,” writes singer and actress Taylor Swift.

"How do you see blue and black???" - asks actress and fashion model Kim Kardashian.

Lady Gaga also did not stand aside: "The dress is white with sand."

"Guys, what's wrong with you! It is white and blue,” says Oscar-winning Julianne Moore.

People were divided into teams with the hashtags "white-gold" and "blue-black". The hashtag #thedress topped the top trends in the States. And everyone is scared. Voting took place on various sites. For example, on buzzfeed.com, which first wrote about this story, 72% voted for white and gold. 28% - for the second option. On telegraph.co.uk, 42% of voters see blue-black.

It has already turned out that in the original dress is really blue and black. But why do some users see it as white and gold?

Ophthalmologists tried to explain why people see the dress differently

Your retina is made up of rods and cones that convert light stimuli into neural stimulation. They convert the signal differently. Rods are more sensitive to light, see shadows and work more efficiently in the dark. Cones are sensitive to color, but less sensitive to light. That is, in low light conditions, you see more with rods than with cones.

The dress appears blue-black or white-gold depending on whether your eye has more rods or cones and the lighting conditions in the room. Different people have different ratios of rods and cones.

It takes about 45 minutes for your vision to readjust (as your eyes take time to adjust to the dark). If you look at a dress in bright light and see one color, it might change if you go into a dark room for half an hour and then come back.

Also, the different color of the dress for different people is associated with individual differences in color perception. If you've ever tried photography, you've probably come across white balance: the camera tries to equalize it in inappropriate lighting conditions. Your brain does its own white balance, which means you are either oblivious to blue tint, you see a white-and-gold image, or, ignoring the yellow tint, you see a blue-black photo.

Ophthalmologists say that a different perception of the color of a dress does not mean that you have vision or mental problems. Each person has an individual vision. The brain processes the light waves that hit the retina in a unique way, so some people see certain colors and others see different colors.

There is another explanation for why people see different colors in one picture. This is optical illusion. Objects reflect light at different wavelengths or in different colors, and the human brain determines the color from the reflected light. Objects around can also reflect color and affect perception. There are a lot of colors around in this photo and they mix - the brain cannot immediately determine the color of the dress. People who perceive ambient light as dark see white instead of blue. University of Washington professor Jay Neitz says he has been studying color difference for 30 years and this case is one of the most striking. By the way, the dress seemed white to him.

A new explanation of American scientists who have conducted a study of this phenomenon is possible.
