Here, though, to some people, the perception is so strong that even the idea of a blue tint is sometimes discounted. Fig 1 The Dress as seen on the internet shown in A and the actual blue and black dress is shown in B. C shows an extracted image of the Dress consisting of vertical stripes of decreasing spatial frequency that was used in the present study to explore perception of the dress with limited contextual cues.
For about half of us, the brain discounts the blue side of the light source, subtracting out the blue from the actual color of the dress so that we perceive the dress as white and gold. For the rest of us, the brain discounts the gold spectrum of the light, yielding a totally different perception of the dress as that of a blue and black dress. For reasons reviewed above, our second hypothesis was that people with previous experience of The Dress would be less likely to choose “there is no correct answer” to the question “What is the correct answer? ” about The Dress’ colors, compared to people who have not seen The Dress before .

Additionally, the retailer of the dress produced a one-off version of the dress in white and gold for charity. 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. So, the controversial picture of the dress is not blue/black, nor is it white/gold—it is neither. There is an objective fact about what wavelength of light it emits from your computer screen, but that wavelength of light is interpreted in different ways by different brains. But the weird thing is how certain I was it was black and blue and how certain my father was that it was gold and white. What a marvelous moment it was for me to realize no one was really “right or wrong”….
But what causes it to reflect that wavelength is not its “being a certain color.” It’s ultimately because its molecular structure interacts with light in a certain way—a way such that some frequencies are absorbed and others are reflected.

In memory research it has been found that memories of events where people have no own recollection to rely on can be considered very plausible (for example the memory of a parent’s story about something that happened to a child). On the other hand, people can have own vivid recollections of visual detail, that they consider less plausible, and these memories may be non-believed . In case of The Dress, participants who believe “blue and black” is the correct answer, despite recently seeing “white and gold” may refer to other people’s judgments. For example, The Dress is typically considered blue and black in real life (e.g., Akbaerian, 2015) and it is possible that memories of such knowledge can affect beliefs about the correct answer.
Interestingly, older people and women were more likely to see the dress as white and gold, as opposed to blue and black. This could be because older people and women may be more likely to be active during the day, while younger people and men may be more likely to spend time around artificial light sources, the researchers said. Researchers also added that older people and women were more inclined to see the dress as white and gold, as opposed to blue and black. This is because older people and women are more inclined to be active during the day, while younger people and males spend more time around artificial light sources. People who saw a white-gold dress assumed it was lit by daylight, so the brain ignored shorter, blue wavelengths.

Thus, if a person initially has a belief that is in contrast to the majority of trusted others (e.g., “white and gold” in contrast to a majority of “blue and black”), they may conclude that the question is not possible to answer. Experience of the photograph may also be related to increased knowledge about the possible variation in color perception of the photograph. For example, our finding that participants seeing “blue and black” were less likely to report “there is no correct answer” suggest that previous perceptual experiences may be related to answerability judgments.
We compensate to make the same color brown appear lighter in shadows - neuroscientists call that discounting the chromatic bias. The shadow makes the color of two identical blocks look like different colors. McNeill, who asked for help in deciding what colour the dress was as she and her friends couldn't agree. Twitter rushed to help and soon #TheDress was trending worldwide. The simple perfection of quantum correlation in human vision. The colorimeter positioned over the 22” LCD display with magnified components of the Dress image.

However, it is the brain that constructs our perception of reality for us. Differences exist between individuals in sensory and perceptual processing, as well. This means that we may not all be experiencing the same reality – as is the case with the now famous blue and black or white and gold dress. Comparison between participants who had seen, and not seen, The Dress photograph.
Modern researchers have come up with theories on how our eyes adjust to different colors in clothing, and how that affects what we think about the meaning of the dress. Lacking L or M cones has minimal impact on perceived dress colors while a lack of S cones yields a very different perception suggesting a primary role of the S cone input in perception of the Dress. Similar theories have been expounded by the University of Liverpool's Paul Knox, who stated that what the brain interprets as colour may be affected by the device the photograph is viewed on, or the viewer's own expectations. Anya Hurlbert and collaborators also considered the problem from the perspective of colour perception.
