Meet 2017's iteration of that dress: a chest of drawers. It's arrived just in time for the holidays, but hey, at least it's better than fighting about politics.
Rather than argue about healthcare and tax bills, you can now force your relatives into a debate about the color of a piece of bedroom furniture while indulging in some turkey and mulled wine.
Is it pink and white? Or is it blue and grey? (It's definitely pink and white.)
The person responsible for bringing this mind-bending piece of furniture to the Internet's attention is a Reddit user called agamiegamer. They posted the offending picture to the site on Monday under the title “What Colour Do You See: Pink & White or Blue & Grey?”
While some people are convinced it is pink and white...
Others will tell you it's most certainly blue and grey...
And there are those who disagree completely.
Some people just want this whole business to go away. (I mean, who can blame them?)
And there are those who are far more concerned about that knob situation.
This debate keeps popping up in some form or another. In 2015, we had the dress. In 2016, it was a pair of flip-flops. Earlier this year, there was the Nike outfit. And now, this. So what is going on?
Well, according to Pascal Wallisch, a clinical assistant professor of psychology at New York University, whose research was published in the Journal of Vision earlier this year, it may have something to do with your sleeping preferences.
When we're presented with an image, our brain has to make a quick assessment of the context or surroundings of the object (is it daytime or nighttime, for example). In each of these photos, very little context is given and our brain has to do its best with the minimal information there is – hence the confusion.
Based on 8,084 people's survey results, Wallisch found that "strong larks" (or early risers) were more than 11 percent likely to say the dress is white and gold compared to "strong owls" (or late sleepers), who were more likely to say they thought it was blue and black. This increased to 40 percent in the second survey, which involved 5,333 participants.
He suggests that this is because early risers – who naturally see more daylight – will "see" the dress under natural light and therefore subconsciously interpret it as white and gold. Late risers – who see more artificial light – will instead "see" the dress under artificial light and interpret it as black and blue.
However, the science is still not entirely settled.
So what color is the chest of drawers really? Let us know your thoughts in the comments.
