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. False color illusions are images that deceive the eye into believing that the colors around them are the same. When we see something, light moves through our eye in various wavelengths, corresponding to the colors we see. The brain computes the magnitude of the color light that is bouncing off of the object by subtracting the actual color from the color of the object.
For his study, Webster asked college students whether they saw the dress’s stripes as blue or white. But when the team inverted the colors of the dress, the blue/white stripes became unambiguous shades of yellow, and nearly 95 percent of the students identified the dress as yellow and black. In one study, Michael Webster, a psychologist from the University of Nevada, Reno, places blame for Dressgate on the ambiguity of the color blue, and people’s inability to reliably discern blue objects from blue lighting. He said that our vision was good at telling if we were looking at a white paper in red light, or a red paper in white light, but that process did not work easily for all colors, and blue tends to be problematic. "The checkerboard illusion involves just black and white, but the idea extends to the color of the dress," he said. "The main point is that we can't tell the difference between white and blue, or between black and gold, unless we have some independent information about the wavelengths of light illuminating the dress."

On 28 February, Roman announced that they would make a single white and gold dress for a Comic Relief charity auction. 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. We have three types of cones, each tuned to pick up green, red, or blue wavelengths of light.
Those who saw it as a blue-black shade assumed a warm, artificial light, so their brains ignored longer, redder wavelengths. Those who saw the dress as a blue-brown color probably assumed neutral lighting, the researchers said. The vast majority of subjects reported no difference in their BB vs. WG perceptions between the iPhone, iPad, 22” LCD display, and extracted stripe images of the Dress . One BB subject reported that the tablet Dress appeared blue and gold, another BB reported that the stripe pattern appeared blue and gold, and one WG subject reported that the stripes appeared blue and gold. Hence the majority of observers perceived the same Dress colors regardless of display.

The study asked 1,401 people (313 of whom hadn’t seen the dress image before) about the color of the garment. Out of the people surveyed, 57 percent of the people described it as blue/black, with 30 percent describing it as white/gold. There were also people, 11 percent of them, who described it as blue/brown and 2 percent saw something else. Natural light has a similar effect—people who thought it was illuminated by natural light were also more likely to see it as white and gold.
It appears to be because of different interpretations of how the scene is illuminated. The brain automatically “processes” visual input before we consciously perceive it. Differences in this processing between people may underlie The Great Dress Debate. Explanations on why you see what you see range from the settings on your monitor to the lighting in the room and even the inner workings of the human eye and brain. "The photos will come out the same. How could they not?" he said. "People, however, can usually see the difference, if there is some clue they can find that tells them the color of the light illuminating the room."
What color is the jacket really?
“It caught fire because it was a case in which color wasn’t doing what we expect,” says Conway, who teaches at Wellesley College and the Massachusetts Institute of Technology. By 1 March, over two-thirds of BuzzFeed users polled responded that the dress was white and gold. Some people have suggested that the dress changes colours on its own. Media outlets noted that the photo was overexposed and had poor white balance, causing its colours to be washed out, giving rise to the perception by some that the dress is white and gold rather than its actual colours. The lighting of the image, which has a bluish tint, appears to be what is throwing people's brains off. I then decided to focus really hard on the middle of the dress, despite being exhausted, and after a few seconds the dress slowly turned black and blue again.
Your girls will love hitting the dance floor in our collection of beautiful dresses. The image below, tweeted by @namin3485, demonstrates that even though the right-hand side of each image is the same, in the context of the two different left halves, the right is interpreted as being either white and gold, or blue and black. Although your eyes perceive colors differently based on color perceptors in them called cones, experts say your brain is doing the legwork to determine what you're seeing -- and it gets most of the blame for your heated debates about #TheDress. A third study, conducted by researchers at the University of Nevada, Reno, recruited 87 college students and asked them to name the colors of the dress.
"You might even change the settings on your screen and see two different colors," Garg said. “There are owls like me who get up very late and stay up very late, who get less daylight exposure. The Dress as seen by a color vision normal observer, protanope, deuteranope and tritanope.
Each subject wore an elastic headband to secure the active electrode in place and electrode impedance was maintained at ?5 kilohms. The VEP stimulus was a high resolution transparency of the original dress image retro-illuminated by a flashing neutral white background (100 cd/m2) from a calibrated VEP monitor . The dress stimulus subtended an angle of 12.2° x 16.2° degrees and was viewed binocularly at 1m in a darkened room with subjects optimally corrected for the viewing distance.
