Media outlets noted that the photo was overexposed and had poor white balance, causing its colours to be washed out, giving rise to the perception by some that the dress is white and gold rather than its actual colours. 'However, artificial light tends to be yellowish, so if we see it brightened in this fashion we factor out this colour - leaving us with a dress that we see as black and blue. Depending on whom you ask, itmight be black and blue or white and gold.
Wallisch came to this conclusion after surveying 13,000 study participants who claimed to have previously seen a photo of the infamous dress about how they thought it was illuminated. Wallisch found that people who thought the dress was in a shadow were more likely to think it was gold and white. The fact is that both of these images contain the exact same colored circles, there is absolutely no difference between the two images except for the background. Put simply, 'larks' - people who rise and go to bed early and spend many of their waking hours in sunlight - are more likely to see the dress as white and gold. And he found that 'larks' - people who rise and go to bed early and spend many of their waking hours in sunlight - are more likely to see the dress as white and gold. "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," she added.

Your brain figures out what colour light is bouncing off the object your eyes are looking at by subtracting that colour from the real colour of the object. You may find this surprising but to some crazy people, the dress above appears to be black and blue. "When you take grey pixels and subtract out this blue bias, you end up with red." If you look really closely, you can see the horizontal top of her leg.
The top one looks brown and the bottom one looks more orange. But if you assume that the front of the dress is well lit , you will see the dress as blue. The eye-brain combination is NOT good at judging the absolute colour of anything, but it's very good at comparing. Really didn't have a solid plan as to what I wanted my hair to look like, but she came up with a beautiful style - and it held up thru my entire evening.
Is the black and blue dress an optical illusion?
Although the dress was eventually confirmed to be coloured black and blue, the image prompted much online discussion of different users' perceptions of the colour of the dress. Members of the scientific community began to investigate the photograph for new insights into human colour vision. The dress is a photograph that became a viral phenomenon on the Internet in 2015.
'Not only did you pass, the fact that you were able to see all the letters across the spectrum proves that you have incredible vision and a particularly trained eye. One dad, 43, was so baffled that he turned to social media, appealing for help in solving the question. But within the scene, six holiday-themed words have been hidden, and the challenge is to spot them all. Sometimes the easiest-sounding brain teasers are the most difficult ones.

Businesses that had nothing to do with the dress, or even the clothing industry, devoted social media attention to the phenomenon. Adobe retweeted another Twitter user who had used some of the company's apps to isolate the dress's colours. "We jumped in the conversation and thought, Let's see what happens," recalled Karen Do, the company's senior manager for social media. Jenna Bromberg, senior digital brand manager for Pizza Hut, saw the dress as white and gold and quickly sent out a tweet with a picture of pizza noting that it, too, was the same colours. The lighting of the image, which has a bluish tint, appears to be what is throwing people's brains off.
Those who see the dress as black and blue may be imagining the dress in an artificially lit room, with yellow light. But it appears white and gold to some people due to a phenomenon called color constancy and the way that our brains interpret colors. It all depends on which information your brain decides to fill in. Most of what we perceive is actually not what we directly see, our brains do a lot of processing to fill in the blanks. But if you see blue and black you realize that the image is somewhat washed out.
Initial viral spread
The puzzle is a slight detour from the current trend of Where's Wally-style quizzes. The words do not correspond with the colour they are written in, for example 'green' is written in blue. Participants are asked how many different colours they can see - excluding white. The gherkin is actually hidden towards the bottom left of the image, behind an onion ring and a beef burger. The visual puzzle was created by illustrator Sally-Ann Heron for food delivery service Deliveroo.
The peer-reviewed Journal of Vision even published several articles about it. "There's no way for me to verify the color that your brain perceives versus the color that my brain perceives," he said. "What I call magenta, you might call violet. What I call burgundy, you might call purple." But your perception of the dress doesn't mean you have an eye problem, she said. Cataracts, colorblindness and eye disease can also alter colors for the beholder. Monet's famous water lily pond painting is thought to have been painted when he was developing cataracts, Lystad said.
