Pomerantz noted that the other big factor in play is "the oversize emotional reaction" the picture has drawn from people on the Internet. Pomerantz said much that has been written about the dress in the last two days has been "silly" or "just plain wrong." It posted more than a half-dozen stories on the image and the tsunami of reaction.
There is currently no consensus on why the dress elicits such discordant colour perceptions among viewers, though these have been confirmed and characterised in controlled experiments . No synthetic stimuli have been constructed that are able to replicate the effect as clearly as the original image. The dress was identified as a product of the retailer Roman Originals, which experienced a major surge in sales of the dress as a result of the incident. The retailer produced a one-off version of the dress in white and gold as part of a charity campaign. The two-tone dress, left, alongside an ivory and black version, made by Roman Originals, that has sparked a global debate on Twitter over what color it is on display in Birmingham, England on Feb. 27, 2015. Take a look at the original, but stare at it for around 30 seconds.
The Dress: Is It White And Gold Or Blue And Black?
Conway concludes that the differences in color perception are the result of the assumption our brain makes out about the illumination of the objects and the source of their lightning; a property known as color constancy. As already discussed, individuals who spend most of their waking time at night were probably more attuned to the subtle light difference in the photo. It is possible that most night-owls saw the dress to be the color it actually was!
Another finding from the survey was that perception differed by age and sex. Older people and women were more likely to report seeing “The Dress” as white and gold, while younger people were more likely to say that it was black and blue. Friends and co-workers worldwide are debating the true hues of a royal blue dress with black lace that, to many an eye, transforms in one photograph into gold and white. A study carried out by Schlaffke et al. reported that individuals who saw the dress as white and gold showed increased activity in the frontal and parietal regions of the brain. These areas are thought to be critical in high cognition activities such as top-down modulation in visual perception. On the day of the wedding, Caitlin McNeill, a friend of the bride and groom and a member of the Scottish folk music group Canach, performed with her band at the wedding on Colonsay.

"You might even change the settings on your screen and see two different colors," Garg said. But I've studied individual differences in colour vision for 30 years, and this is one of the biggest individual differences I've ever seen. And now that the digital age is here, there are subtle differences between how something can appear to you on a television screen versus a computer monitor versus a cell phone, Calkins said. "There's no way for me to verify the color that your brain perceives versus the color that my brain perceives," he said. "What I call magenta, you might call violet. What I call burgundy, you might call purple."
And your eyes send the signals they do because of the way wavelengths of light interact with their rods and cones. But, again, it's not like different wavelengths of light are actually different colors. People all over the world are debating if this dress is blue or black, or gold or white. "There's no correct way to perceive this photograph. It sits right on the cusp, or balance, of how we perceive the color of a subject versus the surrounding area," he said. "And this color consistency illusion that we're experiencing doesn't mean there's anything wrong with your eyes. It just shows how your brain chooses to see the image."
What does it mean if you see white and gold on the dress?
And that was on three screens with a photographer's eye. According to Beau Lotto, the brain is doing something remarkable and that's why people are so fascinated by this dress. Basically, one of the colors falls on the black/gold border and the other falls on the blue/white border.
The brain automatically “processes” visual input before we consciously perceive it. Differences in this processing between people may underlie The Great Dress Debate. There are many cues to depth, and together they limit how good an estimate of depth your visual system can provide.
Our perception of color depends on interpreting the amount of light in a room or scene. When cues about the ambient light are missing, people may perceive the same color in different ways. Make it pretty obvious that at some point your brain switches from wanting to see blue to wanting to see yellow based on the color context. It would appear some of us are slightly different in where transitions like that occur.
The truth is the colors of the dress in the photograph are a murky brown and a greyish lavender. Whether you see the dress as blue and black or gold and white depends on how your brain is interpreting the scene. While the cones in our eyes are the receptors of color information, it’s our brain that compares the signals from the cones and produces an impression of colors. It looks to cues in the scene to interpret the real color of an object no matter what the illumination. It’s called color constancy and it’s why you know a white car is white even if it’s sunset and reflecting orange or nighttime and in dark blue shadow. The blue and black dress illusion is one of the most famous optical illusions of all time.
