Remember #dressgate and the outfit that was white and gold lace to some and black and blue to other? Well, get ready for a sequel that’s going to leave you just as stumped.
It comes courtesy of Nicole Coulthard, who posted an image to the Facebook group Girlsmouth that’s left pretty much everyone stumped.
Coulthard wrote alongside the image: “Ok girls so my friend has just sent me this asking what colour the shoe is, I would say pale pink and white, but she insists its pale blue and grey. ‘What do you girls see? Please tell me pink and white!”
Unfortunately for Nicole, nearly half as many people saw the trainers as grey and aqua as they did pink and white, prompting a massive debate over the entire thing.
So how does this happen?
When the #dressgate debate was first raging, scientists decided to uncover the truth. A group of volunteers were put in an MRI scanner and asked to look at the image of the dress.
The scientists observed several subtle changes in how the brain functioned. Those who saw the original dress as white and gold had extra activity in the front and parietal areas of the brain, which play an important role in mental reasoning, visual perception and selective attention.
So their brains were basically working extra hard to make sense of the image with the blue colour instead appearing as a shadow on a white dress.
Though the dress was officially blue and black lace, because colour is merely a perception created by the brain when light hits the retina, certain images can often appear a different colour to different people.
