"It looked white and gold, now it looks blue and black," one man told CBS'2 Ilana Gold. Wallisch came to this conclusion after surveying 13,000 study participants who claimed to have previously seen a photo of the infamous dress about how they thought it was illuminated. Wallisch found that people who thought the dress was in a shadow were more likely to think it was gold and white. A superficial controversy, to be sure, yet one that underscores serious scientific questions in neuroscience that are related to perception, and the ability of human vision to distinguish surface colors under different lighting conditions. Our eyes contain a layer of tissue called the retina, which enables our vision. Our eye’s photoreceptors receive light rays from the sun and convert this into nerve signals.
Therefore, arguably, people who originally saw it this way have better colour constancy. They were able to take cues from the background and compensate for the very unnatural illumination. There is evidence that people with good colour constancy also have better working memory and that these two processes may be related. Other photographs show that the dress is actually blue and black.

Nless you live under a rock, you’ve likely heard about the “The Dress” (if you don’t know what The Dress is, read this). It puzzled some researchers too, but now a team of scientists have published a new study shedding light on the phenomenon. Now, you see the leaf as green because it absorbs certain wavelengths of light and reflects others. The fact that it reflects a wavelength between 495 to 570 nm is why you see it as green. 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.
This is why men often wear black suits when visiting doctors's offices or other places where they need to look small. It also helps men feel less vulnerable if they know they are wearing something dark. Heaven and earth are two parts of our world separated by distance but connected by relationship. They are opposite forces within nature but both are essential for life. Blue represents heaven while gold represents earth - the first thing we feel when waking up and the last thing we remember before falling asleep.

The cones in our retina provide us with day vision and color perception. 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.
Half the people on social media see this dress as blue and black and the other half see it as yellow and gold. How can we be perceiving such different colors in the same object? This debate is reminiscent of themes from the movie The Matrix, in which the protagonist Neo realizes that our brains are the source of all of our perceptions and, essentially, of our individual reality.
Party Dresses
"#TheDress" was the world's most popular hashtag Thursday night and early Friday. "I showed my band ... who were playing at the wedding with me, and we all fell out trying to decide what the problem was," McNeill said. "We almost didn't make it on stage because we were so caught up discussing this dress." McNeill is a member of the folk band Canach and said she got the now-famous pic before playing a wedding, where the bride's mother planned to wear the dress.
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. "I couldn't open Twitter because it kept crashing. I thought somebody had died, maybe. I didn't know what was going on." Later in the evening the page set a new record at BuzzFeed for concurrent visitors, which would reach 673,000 at its peak. Pretty blue things can often be mistaken for beautifully golden and white hued, then?
Light is made up of different wavelengths, which the brain perceives as color. Light entering the retina, the light-sensitive part of the eye, activates cone cells that are sensitive to either red, green or blue wavelengths. But the wavelengths your eye detects may not be the wavelengths of the object you're looking at. 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.
Another related movie is Inception, another movie about altered perceptions and beliefs about reality. The dress is a photograph that became a viral phenomenon on the Internet in 2015. Viewers of the image disagreed on whether the dress depicted was coloured black and blue, or white and gold. 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. 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.
