The dress of many colours: is it blue and black or white and gold?

A recent debate on the colour of a dress has broken the internet. But is it all just a visual illusion?

The internet went Armageddon last night over the colour of an (let’s face it) ugly dress which Tumblr user swiked uploaded. The disagreement in colours divided the social media world: is it blue and black or white and gold or something in between?

(By the way, it’s clearly blue and black.)

When things start to question our existence we turn to science to tell us things are going to be ok. Let’s turn to how our brains translate colour through our retinas:

Visible light can be broken down into various wavelengths which correspond to different perceivable colours. This all depends on what colour(s) the object is reflecting. This reflective light enters through the eye lens and hits a light sensitive layer of tissue called retina in the back of the eye where a cascade of neural messages are sent to the visual cortex – the part of the brain that processes visual information. However, the quality of light that penetrates into our retina plays a big part.

Luminance is the intensity of light emitted from a surface per unit area of light travelling in a given direction. So the brain has to work out how much of the luminance (or lack thereof) is caused by the colour of the square and how much is caused by the shadows. “In the case of the dress, some people are deciding that there is a fair amount of illumination on a blue and black (or less reflective) dress. Other people are deciding that it is less illumination on a white and gold dress (it is in shadow, but more reflective),” said Cedar Riener, an associate professor of psychology at Randolph-Macon College in a BuzzFeed interview.

An example is the famous Adelson checkerboard optical illusion, in which square A and square B are same shade of grey: 

 

 

So why do different people’s brains interpret light differently? Humans have evolved to see in the daylight. Typical daylight extends from blue-white at noon to pinkish-red at dawn. Bevil Conway, a neuroscientist who studies colour at vision at Wellesley College told Wired: “What’s happening here is your visual system is looking at this thing, and you’re trying to discount the chromatic bias of the daylight axis. So people either discount the blue side, in which case they end up seeing white and gold, or discount the gold side, in which case they end up with blue and black.”

Conway also suggests that the white-gold or blue-black bias could be linked to whether we prefer daylight or night time. So those who perceive the dress as white-gold might be interpreting it as though it's in blue natural lighting, and those who perceive it as blue-black might be interpreting it as though it's in yellow artificial lighting. “I bet night owls are more likely to see it as blue-black,” Conway says.

Based on correct white-balancing, we can confirm that the dress is blue and black (sorry white and gold die-hards), but ultimately, visual perception is in the eye of the brain holder.

Luckily for the New Statesman, Ed Miliband established Labour's position on the blue-black and white-gold spectrum:

Clickbaiting terror: what it’s like to write viral news after a tragedy

Does the viral news cycle callously capitalise on terrorism, or is it allowing a different audience to access important news and facts?

On a normal day, Alex* will write anywhere between five to ten articles. As a content creator for a large viral news site, they [Alex is speaking under the condition of strict anonymity, meaning their gender will remain unidentified] will churn out multiple 500-word stories on adorable animals, optical illusions, and sex. “People always want to read about sexuality, numbers of sexual partners, porn habits and orgasms,” says Alex. “What is important is making the content easily-digestible and engaging.”

Alex is so proficient at knowing which articles will perform well that they frequently “seek stories that fit a certain template”. Though the word “clickbait” conjures up images of cute cat capers, Alex says political stories that “pander to prejudices” generate a large number of page views for the site. Many viral writers know how to tap into such stories so their takes are shared widely – which explains the remarkably similar headlines atop many internet articles. “This will restore your faith in humanity,” could be one; “This one weird trick will change your life…” another. The most cliché example of this is now so widely mocked that it has fallen out of favour:

You’ll never believe what happened next.

When the world stops because of a tragedy, viral newsrooms don’t. After a terrorist attack such as this week’s Manchester Arena bombing, internet media sites do away with their usual stories. One day, their homepages will be filled with traditional clickbait (“Mum Sickened After Discovery Inside Her Daughter’s Easter Egg”, “This Man’s Blackhead Removal Technique Is A Complete And Utter Gamechanger”) and the next, their clickbait has taken a remarkably more tragic tone (“New Footage Shows Moment Explosion Took Place Inside Manchester Arena”, “Nicki Minaj, Rihanna, Bruno Mars and More React to the Manchester Bombing”).

“When a terrorist event occurs, there’s an initial vacuum for viral news,” explains Alex. Instead of getting reporters on the scene or ringing press officers like a traditional newsroom, Alex says viral news is “conversation-driven” – meaning much of it regurgitates what is said on social media. This can lead to false stories spreading. On Tuesday, multiple viral outlets reported – based on Facebook posts and tweets – that over 50 accompanied children had been led to a nearby Holiday Inn. When BuzzFeed attempted to verify this, a spokesperson for the hotel chain denied the claim.

Yet BuzzFeed is the perfect proof that viral news and serious news can coexist under the same roof. Originally famed for its clickable content, the website is now home to a serious and prominent team of investigative journalists. Yet the site has different journalists on different beats, so that someone writes about politics and someone else about lifestyle or food.

Other organisations have a different approach. Sam* works at another large viral site (not Buzzfeed) where they are responsible for writing across topics; they explains how this works:  

“One minute you're doing something about a tweet a footballer did, the next it's the trailer for a new movie, and then bam, there's a general election being called and you have to jump on it,” they say.

Yet Sam is confident that they cover tragedy correctly. Though they feel viral news previously used to disingenuously “profiteer” off terrorism with loosely related image posts, they say their current outlet works hard to cover tragic news. “It’s not a race to generate traffic,” they say, “We won't post content that we think would generate traffic while people are grieving and in a state of shock, and we're not going to clickbait the headlines to try and manipulate it into that for obvious reasons.”

Sam goes as far as to say that their viral site in fact has higher editorial standards than “some of the big papers”. Those who might find themselves disturbed to see today’s explosions alongside yesterday’s cats will do well to remember that “traditional” journalists do not always have a great reputation for covering tragedy.

At 12pm on Tuesday, Daniel Hett tweeted that over 50 journalists had contacted him since he had posted on the site that his brother, Martyn, was missing after the Manchester attack. Hett claimed two journalists had found his personal mobile phone number, and he uploaded an image of a note a Telegraph reporter had posted through his letterbox. “This cunt found my house. I still don't know if my brother is alive,” read the accompanying caption. Tragically it turned out that Martyn was among the bomber's victims.

Long-established newspapers and magazines can clearly behave just as poorly as any newly formed media company. But although they might not always follow the rules, traditional newspapers do have them. Many writers for viral news sites have no formal ethical or journalistic training, with little guidance provided by their companies, which can cause problems when tragic news breaks.

It remains to be seen whether self-policing will be enough. Though false news has been spread, many of this week’s terror-focused viral news stories do shed light on missing people or raise awareness of how people can donate blood. Many viral news sites also have gigantic Facebook followings that far outstrip those of daily newspapers – meaning they can reach more people. In this way, Sam feels their work is important. Alex, however, is less optimistic.

“My personal view is that viral news does very little to inform people at times like this and that trending reporters probably end up feeling very small about their jobs,” says Alex. “You feel limited by the scope of your flippant style and by what the public is interested in.

“You can end up feeding the most divisive impulses of an angry public if you aren’t careful about what conversations you’re prompting. People switch onto the news around events like this and traffic rises, but ironically it’s probably when trending reporters go most into their shells and into well-worn story formats. It’s not really our time or place, and to try and make it so feels childish.”
