Simply put by IFL Science, it means that “the context, or surroundings, in which an object we are looking at appears in, influences our perception of its colour”. So, the environment in which people assume the photo has been taken can affect the hues they see on screen. In the scientific world, this is called top-down processing. In the case of The Dress, researchers suggest that the differences in opinion on the colours depend on whether the viewer believes the photo was taken inside or outside. Another finding from the survey was that perception differed by age and sex.

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. The phenomenon originated from a washed-out colour photograph of a dress posted on the social networking service Facebook.
These areas are thought to be critical in high cognition activities such as top-down modulation in visual perception. The first thing to notice is that the dress is backlit, leaving the dress in shadow. Your brain is familiar with the Purkinje effect on a subconscious level, and it knows that in shadowy, dim lighting, white things often look silvery blue. If your brain has decided to perceive this image primarily as dimly-lit, you subconsciously cancel out the bluish tinge of the dress and see the white. A similar effect happens with the gold-or-black panels on the dress.

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. So why are a lot of people noticing the image flipping back and forth between the colors?
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. Then I let my eyes be tired, and after some time the dress became white and gold. Wired has even looked at the science behind why people are seeing the dress as gold and white, blue and white, blue and blue or blue and black. People who see white and gold may be looking at the dress in a blue-lit room or near a window with a blue sky.

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. 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. Other photographs show that the dress is actually blue and black.
Buzzfeed's online story about the dress has been shared more than 20 million times. Prof Westland explained that the confusion could stem from how we name colours, as there are often blurred lines between how we interpret what colour something is. Prof Westland said that the "strange" lighting in the picture had probably contributed to the confusion. The physiological basis for colour constancy is thought to involve specialised neurones in the primary visual cortex that compute local ratios of cone activity. Kanye and Kim just disagreed on the color of the dress. Want to wait for the best possible deals on designer clothes, shoes and accessories?
The Twitter user in question possibly misinterpreted the widespread belief that colors affect emotions in taking advantage of a viral phenomenon. Dr. Reega Garg, an ophthalmologist at Mt. Sinai, said we're highly sensitive to the color blue and the cells in our eyes cause people to interpret the picture differently. She adds the black stripe can also throw off the color.
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. 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. Our visual system discounts the information about the light source so that we process the colors of the actual object being viewed. 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.
