Whether you were part of team blue and black or white and gold, the phenomenon definitely had us all questioning how it was possible to see the world in such contrasting ways.

And there was even some mind boggling science that emerged in the aftermath.

“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,” says Bevil Conway, a neuroscientist who studies colour and vision at Wellesley College.

“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.”

Hmmm if you’re still scratching your head after that explanation, you’re not alone! But just when you thought it was all over, another puzzle has stepped in to take it’s place.

Falsiane, a Portuguese Twitter account, posted an image of these flip flops last week.
