White And Gold, Or Blue And Black? Social Media Explodes Over Dress

"The information in the picture is ambiguous. People arrive at different interpretations of the lighting in the scene and how light flows...to the dress and eventually the eye. The photoreceptors convert light rays into nerve signals, which are then processed by nerve cells in the inner retina, sent to the brain, and translated as images. “The wavelength composition of the light reflected from an object changes considerably in different conditions of illumination. Nevertheless, the color of the object remains the same,” writes Science Daily.

Cataracts, colorblindness and eye disease can also alter colors for the beholder. Monet's famous water lily pond painting is thought to have been painted when he was developing cataracts, Lystad said. Objects appear reddish at dawn and dusk, but they appear blueish in the middle of the day, Stokkermans said. "Everyone went to DEFCON 5 immediately when someone disagreed. It was like you were questioning something even more fundamental than their religion," Wired articles editor Adam Rogers said. In applying his findings to eye diseases, researchers could determine whether--and how--individuals compensate and change their eye movements over the course of the illness, he says. This process, which neuroscientists call "cue combination," occurs in a fraction of a second as people constantly process information in the environment and decide what to do with it.

Is The Dress Blue and Black or White and Gold? How It Went Viral

Our eyes are able to assign fixed colors to objects under widely different lighting conditions. But the photograph doesn’t give many clues about the ambient light in the room. Or is the whole room bright and all the colors are washed out? Different people may pick up on different visual cues in the image, which can change how they interpret and name the colors. If you are fond of pretty blue things, then you will be happy to know that the dress was, in fact, black and blue.

According to Beau Lotto, the brain is doing something remarkable and that's why people are so fascinated by this dress. Another mindblowing creation by Kitoaka shows a girl with two different coloured eyes - which are actually both grey. The bride then posted the picture on Facebook, and her friends continued to debate the color of the dress. So...the real question is what do YOU see --white/gold or blue/black?

I'm actually somewhat baffled that anyone perceives it as white and gold. It's primarily an effect of the camera fooling around with the white balance and contrast/light to try to get a correct image and failed. All participants who saw the dress as white-gold presented additional activation, mainly in frontal and parietal brain areas.

Our visual system discounts the information about the light source so that we process the colors of the actual object being viewed. McNeill explained that the picture was a dress was worn to her friends’ wedding. In the photo, some people see the dress as white and gold while others see it as blue and black.The dress was worn by the bride’s mother. McNeill and her friends first realized there was something different about the dress when the mother sent her daughter the now-famous photo.

Neuroscientist Bevil Conway believes ‘The Dress’ phenomenon marked the greatest extent of individual differences in colour perception ever documented. Generally, we humans tend to have a lower concentration of rods than we do of cones. Our high cone receptor concentration makes it easier for us to see in the light and detect color differences than cats, for instance. Cats and other animals with nocturnal tendencies are blessed with a higher rod receptor concentration in their retinas, which is why, while their night vision might be better than us humans, they are mostly colorblind.

Here's what they told us.The picture was initially posted on Tumblr by a 21-year-old singer named Caitlin McNeill who lives on the tiny Scottish island of Colonsay. Subsequently, the researchers analysed the brain activation in both groups during presentation of The Dress. They demonstrated that in a direct comparison of groups the photo triggered differential brain activation, depending on their perception. In this control condition, no differences between the groups were identified in correctly naming the colours of the squares, nor in brain activation during the presentation of the coloured squares. But even when it's the same photograph, some people see blue, and others see white.

Would “The Dress” have gone viral had it been #greenandblack or #orangeandblack? Not likely, argues cognitive scientist Michael Webster at the University of Nevada, Reno. He believes that the photograph is part of a growing body of evidence showing that the human eye is more likely to confuse blue objects with blue lighting. A superficial controversy, to be sure, yet one that underscores serious scientific questions in neuroscience that are related to perception, and the ability of human vision to distinguish surface colors under different lighting conditions.
