I can only assume that now, two years later, you have very limited interest in being here. When Dr. Webster inverted the colors of the dress, 95 percent of his participants said they saw the colors yellow and black. If your room is North-facing, it will have more gray light with slight blue cast. Simultaneous contrast – the affect of colors against one another. In contrast with your your brown wood, it might look even more blue.

"Our visual system is supposed to throw away information about the illuminant and extract information about the actual reflectance," Neitz said. "But I've studied individual differences in color vision for 30 years, and this is one of the biggest individual differences I've ever seen." For the record, the dress does not have chameleon-like qualities.

"An understanding of either sort of bistability, if that's what this is, would be really cool, particularly if we could figure out how to create and manipulate it in the images."

People are much more likely to perceive a surface as white or gray if the amount of blue varies, compared with similar changes in the amount of yellow, red or green, they added. The combination of black and blue is called "mourning colors". These colors are used to show sympathy or respect during a funeral service. In humans, melanin is found in cells called melanocytes, which are responsible for producing melanin in skin and hair. People of African descent tend to have more melanin than people of European descent, which is why people of African descent can see colors that others don't. Also, women who have had much exposure to sunlight while growing up with no sunscreen often have brown rather than white skin because the melanin in their skin protects them from the sun's harmful rays.

But then again, you can correct the photo in other ways and come to an entirely different conclusion.

In the second study, Karl Gegenfurtner, a psychologist from Giessen University in Germany, had 15 volunteers use a customizable color wheel to show what color they saw on the dress. He found that the pixels of the dress matched with the natural spectrum of blues and yellows we see from sunup to sundown, making it more difficult for people looking at it to tell how the color of the lighting might affect perception. That's what Twitter user Arthur asked his followers, and people are literally arguing over the answer. The brand confirmed that the sandals are blue and dark blue, but that hasn't stopped the internet from debating. Some people see white and gold, others see blue and gray, and the color combinations go on and on. The blue and green stripes are actually the exact same color.

To complete her on stage get-up, the “Bluebird” singer stepped out in glittery sheer tights, classic cowgirl boots, a matching shimmering hat, and accessorized her look with a gold belt and chunky metal rings.

The Dress was one of the most popular internet phenomenon in 2015, which was included multiple times as the fastest growing meme of all time. According to Tom Christ, Tumblr's director of data, at its peak, the image was receiving about 14,000 views a second. Ultimately, the dress received a staggering 4.4 million tweets within its first 24 hours. Ceitlin McNeill, a friend of the couple, was also confused after seeing the dress in person.

In my household, three out of four of us see the dress as white and gold. The dress was included on multiple year-end lists of notable internet memes in 2015. In South Africa, the Salvation Army attempted to re-direct some of the mass awareness generated by the dress towards the issue of domestic violence. Additionally, the retailer of the dress produced a one-off version of the dress in white and gold for charity.

"I see only the white/gold version, not the blue/black version." They also seem to agree that The Dress is pretty fascinating, though they were divided on its importance. Pasacal Wallisch, clinical assistant professor at New York University, said it could be considered the "duckrabbit of colors," in reference to the famous picture that can be seen as either a duck or a rabbit. Limitations of this study include the relatively small number of subjects tested. A larger sample size may provide more definitive evidence for macular pigment and VEP differences.

The researchers found that the colors people reported are the same colors found in daylight — which tends to be bluish at noon and yellowish at dawn or dusk — in agreement with Conway's team. As such, the phenomenon would not have happened if the dress had been red, they said. Someday last year I opened my Facebook app and almost all the posts on the news feed were this photo — “The Dress”. My first reaction was like, “Well it’s just a white and gold dress.

The photo of the dress just happens to hit the sweet spot of ambiguity in terms of lighting and shading. Different people’s brains will therefore make different assumptions and correct for either apparent overexposure or underexposure. Do you have to correct for the glare of bright lights, or the dulling of colors because of shade? Remember, white appear blue when it is shadowed, and our brains correct the blue to white.
