The bride then posted the picture on Facebook, and her friends continued to debate the color of the dress. Some people see a blue and black dress washed out in bright light. The color of clothes has been the subject of much speculation and lore. The ancient Greeks believed that white garments would protect against the evil eye; dark colors such as black were thought to bring good luck. 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. In humans, melanin is found in cells called melanocytes, which are responsible for producing melanin in skin and hair.
You may have gathered this by now, but what we are experiencing is really a colour illusion. Colour illusions are images where the object’s surrounding colours trick the eye into incorrectly interpreting the colour. Those who originally saw The Dress as blue and black should not be too smug, though. Some may argue that colour itself is just a construct imposed by the brain to make sense of the world.
White and gold? Blue and Black? 'The dress' sets the Internet on fire with massive worldwide debate
The phenomenon revealed differences in human colour perception, which have been the subject of ongoing scientific investigations into neuroscience and vision science, producing a number of papers published in peer-reviewed scientific journals. The Journal of Vision, a scientific journal about vision research, announced in March 2015 that a special issue about the dress would be published with the title A Dress Rehearsal for Vision Science. The first large-scale scientific study on the dress was published in Current Biology three months after the image went viral.
I am pretty confident that there are two different versions of the same picture being passed around just to fuck with people. 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.
What’s the trick behind the black and blue dress?
It makes sense for the light to be red-tinted as the illumination source is the sunrise. All of our perceptual experiences are informed by this kind of processing, resulting from context and previous knowledge. When cues about the ambient light are missing, people may perceive the same color in different ways. Within a half-hour, her post attracted some 500 likes and shares. The photo soon migrated to Buzzfeed and Facebook and Twitter, setting off a social media conflagration that few were able to resist. For instance, people who live in snow all year round above the Arctic Circle have several names for different colors of snow, but to most of us, snow is just snow.
Remember, white appear blue when it is shadowed, and our brains correct the blue to white. Our brains can correct the reflective part of the dress darker to be black, or the dark parts of the dress lighter to appear gold. Now, scientists also think that people’s familiarity with the amount of light in a given environment may guide their judgments about color. Hence, people who are more frequently exposed to daylight are more likely to make adjustments to their judgments about a wavelength by thinking about how daylight will interact with the wavelength. That is how some people reach a decision about the color they see and therefore perceive the dress as gold and white. In contrast, those who are more frequently exposed to artificial or incandescent light do not make these mental adjustments and perceive the color of the dress as it is – blue and black.

How many people started arguements over this dress until they realized there were different levels of truth in regard to this dress? We are so very right that we forget to be aware as to the possibilities of different rights or different wrongs. The original dress photo, with colour treatments that may help explain why people see different colours. "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."
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. They attributed the differences in perception to individual perception of colour constancy. "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."
What Color Is This Dress? It’s An Optical Illusion
Perhaps, but if the informal Internet polling is even remotely accurate, the numbers just don't add up to suggest color blindness is at play. The medical literature suggests that less than 10 percent of the population is afflicted with some form of color blindness—certainly not half of us, let alone nearly three-quarters of all humans.
"Color science has captured the imagination of the universe," he told CBS News. Human beings evolved to see in daylight, but daylight changes the colour of everything we see. Human eyes try to compensate for the chromatic bias of daylight colour. 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.
