He attributes differential perceptions to differences in illumination and fabric priors, but also notes that the stimulus is highly unusual insofar as the perception of most people does not switch. If it does, it does so only on very long time scales, which is highly unusual for bistable stimuli, so perceptual learning might be at play. In addition, he says that discussions of this stimulus are not frivolous, as the stimulus is both of interest to science and a paradigmatic case of how different people can sincerely see the world differently. The philosopher Barry C. Smith compared the phenomenon with Ludwig Wittgenstein and the rabbit–duck illusion, although the rabbit-duck illusion is an ambiguous image where, for most people, the alternative perceptions switch very easily. In February 2015, a photograph of a dress went viral on the internet, sparking a debate over its color.

Anya Hurlbert and collaborators also considered the problem from the perspective of colour perception. They attributed the differences in perception to individual perception of colour constancy. 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.

For example, fluorescent lights give off a higher percentage of yellow light than what is found in the color spectrum of daylight. However, we don’t see everybody and all things as yellow-tinged when we are indoors under fluorescent lighting conditions. The brain works to subtract out the extra yellow, in other words to compensate for the colors present in the light rays of the illuminant in order to yield our ultimate perception.

Basically, when looking at the photo of the dress, our brains are trying to figure out if it’s a blue/black dress in yellow light or a white/gold dress with a blue shadow over it. 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.

The phenomenon originated from a washed-out colour photograph of a dress posted on the social networking service Facebook. Within a week, more than ten million tweets had mentioned the dress, using hashtags such as #thedress, #whiteandgold, and #blackandblue. Although the dress was eventually confirmed to be coloured black and blue, the image prompted much online discussion of different users' perceptions of the colour of the dress. Members of the scientific community began to investigate the photograph for new insights into human colour vision.

Holderness showed the picture to other members of the site's social media team, who immediately began arguing about the dress's colours amongst themselves. After creating a simple poll for users of the site, she left work and took the subway back to her Brooklyn home. When she got off the train and checked her phone, it was overwhelmed by the messages on various sites. When we view an object, the light source reflects off of it and the light waves that reach our eye are processed by photoreceptors in the retina. These photoreceptors send information to our brain, which then constructs our perception of the object. Their findings, detailed on May 14 in the journal Current Biology, suggest the difference in perceived color has to do with how the brain perceives colors in daylight.

Our visual system discounts the information about the light source so that we process the colors of the actual object being viewed. In our everyday lives, there are many changes in the colour of the light illuminating our surroundings. For example, the yellow glow of an incandescent light bulb versus the blue-ish hue of a fluorescent light. The light that an object reflects to the eye is a combination of both the colour of the object itself and the spectrum of the light source, which may vary.

"We discovered a novel property of color perception and constancy, involving how we experience shades of blue versus yellow," the researchers wrote in the study. Then, the researchers inverted the image so that the lighter stripes appeared gold and the darker stripes appeared blue. Now, nearly 95 percent of the participants reported seeing the lighter stripes as "vivid yellow." The researchers confirmed these findings in another group of 80 participants. For example, say you know your mug is white, but the light being reflected from the mug is slightly red. The brain can then discount a certain amount of red tint from the rest of the scene you are seeing. Other contextual knowledge may come into play, for example you are drinking coffee by the window at dawn.
