Contrary to others’ suspicion that is is an online photo trick, it is actually human eyes that does the trick. And the dress takes us back to the anatomy of human eye.

As explained by Wired, when light enters the eyes, it passes through a lens then separates it into different wavelengths. As the light hits your retina, it stimulates the neural connections and then gets interpreted by the visual cortex.

Visual cortex will the process the information from eye’s neural connection into an image. Your brain will instantly take off the light bouncing from the object you are looking at and retain the ‘color’ of the object. The way you see things depends on the brightness or dimness of the surroundings.

However, people have different individual color vision. The brain will interpret the context of what you see, if your brain suggest that the background color is dark then the dress will be white, if the background is light, then the dress is blue. Thus, people’s brain interpret the color of the dress in different ways.

Try to change the brightness of your device from dim to very bright and see how the color changes right in front of you. If you print the photo and cut out the background, it is actually blue.

So what can your eyes see on the dress, is it white and gold or black and blue?
