It’s hard to believe, but this dress has become one of the most talked about images on the Internet recently.
A simple “what colour is this dress” has sparked an online debate where mostly women are claiming it to be gold and white, or black and light blue.
But why the disparity?
Light enters the eye through the lens—different wavelengths corresponding to different colours, according to Wired magazine. “The light hits the retina in the back of the eye where pigments fire up neural connections to the visual cortex, the part of the brain that processes those signals into an image.
“Critically, though, that first burst of light is made of whatever wavelengths are illuminating the world, reflecting off whatever you’re looking at. Without you having to worry about it, your brain figures out what colour light is bouncing off the thing your eyes are looking at, and essentially subtracts that colour from the ‘real’ colour of the object.”
