For the lighter stripe, participants reported seeing a continuous range of shades from light blue to dark blue, rather than white and blue, the two dominant colors reported so far. The dress, which is actually was blue and black, was perceived by some to be white and gold. Vision scientists explained, after researching the matter, that the brain can make assumptions about what we are seeing, and those who assumed the dress was shot in a shadow were more likely to see the gold and white colors.
However, it seems unlikely that the strong S cone component determines the actual colors perceived. Finally, VEPs in response to onset presentation of the Dress showed comparable waveforms for BB and WG, but a prolonged latency to the positive peak for WG observers. 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.
The Blue/Black-White/Gold Dress & Questioning Reality
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.
This dress became a viral sensation as people debated online about whether its colors were blue and black or white and gold. Thus far, research suggests that the difference arises because you use your brain differently. The Dress illusion reminds us of the fallacies inherent in our visual sense and the existence of individual differences in our abilities of perception. So, although the dress is blue and black, your unconscious overthinking makes you see it as white and gold.
New Study Explains Why People Saw 'The Dress' Differently
The dress stimulus subtended an angle of 12.2° x 16.2° degrees and was viewed binocularly at 1m in a darkened room with subjects optimally corrected for the viewing distance. The dress appeared two times per second, with each presentation lasting 250 msec. Each signal was amplified 8X, band-pass filtered (1–30 Hz), and the system computed the average VEP to 70 pattern onsets. Prior to testing, each subject adapted to the white background for about 6 minutes during electrode application.
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. Another related movie is Inception, another movie about altered perceptions and beliefs about reality. We will celebrate five years since The Dress made an impact on our lives on February 20, 2020. What better way to celebrate than by diving into the world of science? Can you tell me which is blue and black or white and gold? The color of The Dress varies depending on whether the viewer believes the photo was taken inside or outside.
The Dress
On 3 March, the Johnstons, Bleasdale, and MacNeill appeared as guests on The Ellen DeGeneres Show in the United States. 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.
For example, if you stare at a gray object and make the gray increasingly yellow or blue, then you’re more likely to see the object as yellow than as blue. This difference likely comes from how the eye evolved in the presence of natural lighting from the sun and the sky. So, individual variations in color perception may not purely be a matter of the nature and number of the cones in the retina. It can also be a result of the fact that people with different numbers of cones calibrate the input from the retina in different ways. The human eye and brain together translate light into color.
Blue and black, or white and gold? Three perspectives on ‘The Dress’
The two-tone dress, left, alongside an ivory and black version, made by Roman Originals, that has sparked a global debate on Twitter over what color it is on display in Birmingham, England on Feb. 27, 2015. As you scan over this image, do you see gray or black dots? It's called a scintillating grid illusion, made by superimposing white discs on the intersections of gray bars against a black background. Dark dots seem to appear and disappear rapidly at the intersections, although if you stare directly at a single intersection, the dark dot does not appear.
Another finding from the survey was that perception differed by age and sex. 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. Natural light has a similar effect—people who thought it was illuminated by natural light were also more likely to see it as white and gold. For people who see the dress as it is — black and blue — you're likely seeing the photo as over-exposed, with too much light, meaning that once the retina registers the image, the colors appear darker. The retailer of the dress confirmed that the real color of the 'Lace Bodycon Dress' was actually blue and black. Tumblr blogger Caitlin posted a photograph of what is now known as #TheDress – a layered lace dress and jacket that was causing much distress among her friends.
