This picture has gone viral – are the trainers pink and white or grey and green? [Twitter]
Another viral picture has got the entire internet both arguing with their friends and wondering whether they need to get their eyes tested.
This time the snap in question features a pair of trainers.
While half of people see the shoes as pink and white in the picture, the other half are convinced these trainers are grey and a shade of green or blue.
And people feel REALLY strongly about the matter.
Over on Twitter, the snap has got everyone talking. One person comically stated: “I showed this to all my classmates and now theyare fighting [whether] it’s pink white or grey.”
Under the snap, one Twitter user firmly stated: “Grey and blue obviously!”
While another chimed in: “Pink and white in every pic iv seen.”
Questioning themselves, a third added: “I hope his is a joke bc where in the hell is teal & grey??”
Twitter is in uproar over these shoes [Twitter]
Meanwhile others have been going back and fourth.
One confused viewer wrote on social media: “Bizarre thing is, I seen them as blue and grey initially then scrolled down, scrolled back up to the very same post and now pink and white!”
This isn’t the first time the same phenomena has overtaken the internet. Remember the white and gold — or blue and black — dress?
Back in February 2015, even celebs were debating online over the garment.
These dress was the original optical illusion that stumped the internet – blue and black or white and gold? [Instagram]
At the time, Taylor Swift took to Twitter to admit she was freaked out by the optical illusion frock, which she is certain is black and blue.
The singer tweeted: “I don’t understand this odd dress debate and I feel like it’s a trick somehow. I’m confused and scared. PS it’s OBVIOUSLY BLUE AND BLACK.
Meanwhile Cheryl shared the snap on Instagram, writing: “This is WHITE AND GOLDDDDD!!!””.
Kim Kardashian West asked: “What color is that dress? I see white & gold. Kanye sees black & blue, who is color blind?”.
The reason behind the optical illusion was later explained. Speaking to Buzzfeed news, Cedar Riener, the associate professor of psychology at Randolph-Macon College, explained: “We are always making decisions about the quantity of light that comes into our retina.”
Named luminance, this light is a combination or how much light is shining onto something we’re looking at, and how much is being reflected off the same object.
He continued: “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/gold dress (it is in shadow, but more reflective).”
And it’s the exact same thing that’s happening with the trainers. Now we’re just waiting to find out who is right…
