At the expense of becoming another sheep in the herd of humanity’s trends, today’s article is going to be about the dress that has invaded the Internet. For those of you who don’t know, ‘the dress’ is a picture of a dress taken at a wedding and published on Tumblr, where it proceeded to reach international fame due to an odd fact: different people see the dress being different colours. It may sound like a weird online hoax, but it’s just an optical illusion that causes some people to see the dress and white and gold, whereas others see it as blue and black. Recently, there have been many theories suggested to explain why this phenomenon happens (for example, because of bad eyesight), but it actually has nothing to do with our eyes, but rather, with our brains. If you’re curious, the actual dress is blue and black, but that doesn’t mean that those who see it in other colours have worse eyesight or worse brains, as you will see.
Think about it like this. When you see an object in the shade, you automatically assume it is of a lighter colour than it actually looks like because you know shade makes things look darker. Therefore, your brain unconsciously tries to compensate for by processing the image your eyes are supplying and making it lighter.
But shade is not the only way images can be distorted. It also happens at normal daylight. If you are observing a piece of paper right underneath the sun, you will be viewing it thanks to a yellowish light. Your brain is smart enough to detect the light has a slight colour of its own and will therefore modify the image and subtract some yellow from it. If, on the other hand, you are seeing the piece of paper with the sun blocked but still receiving light from the sky, the light will be slightly blue, so your brain will take that bluish undertone away.
With this image, it’s the exact same scenario. The dress can appear to be in the shade to some people, and exposed to sunlight to others. Depending on how you unconsciously interpret it, you will see the dress a specific way. Those who think the dress is in the shade will unconsciously think it is darker than it should be, so their brains modify the image and make it lighter. This results in light colours like white and yellow-gold to appear. Those who don’t see the dress in partial darkness keep the colours mostly the same and don’t process the image, making it blue and black.
Interestingly enough, some people see it one way sometimes, the other way other times, and even a mixture of the two! This is just caused by our brains varying the amount of modification they do to the image, and may also have to do with the quality of the screen the picture is being viewed through.
But despite all of this, if you ask me, the dress is obviously white and gold.
