It's definitely white and gold. Or blue and black.

Feb. 26, 2015 will go down in history: A dress broke the Internet. Specifically the colors of one dress.

Some background: Tumblr user swiked uploaded an image of this dress on Wednesday, writing "guys please help me - is this dress white and gold, or blue and black? Me and my friends can't agree and we are freaking the [expletive] out." Other comments in the thread included "So I just looked at this, like it's blue and black obviously and all my friends are like no it's blue and gold. Now I'm super confused, what is eyesight?" and "if that's not gold, my entire life has been a lie" and so on.

BuzzFeed, the god of all things viral, tweeted a photo of the dress with a poll on Thursday evening. By Friday morning, the post What Colors Are This Dress had more than 23 million page views — a record. (Just FYI for team white and gold: 72% of respondents agree. Only 28% said they saw blue and black.)

Later, BuzzFeed tweeted: "HAAAAAAALP" and WILL WE EVER KNOW?"

The madness didn't stop there. Facebook, Twitter and Tumblr users all began sharing the photo and asking what colors people were seeing.

"My boyfriend sees white and gold, I see black and blue. We can't date anymore," tweeted Taylor Smead. "this has been the hardest day of my life," tweeted Adam Ellis.

But then it spread to celebrities, too. "IT'S A BLUE AND BLACK DRESS! ARE YOU [expletive] KIDDING ME?" tweeted Mindy Kaling.

"I don't understand this odd dress debate and I feel like it's a trick somehow. I'm confused and scared. PS it's obviously BLACK AND BLUE," tweeted Taylor Swift.

"What color is that dress? I see white & gold. Kanye sees black & blue. Who is colorblind?" tweeted Kim Kardashian West.

It didn't take long for Internet articles to start showing up dissecting why people were seeing so many different colors.

"Our visual system is supposed to throw away information about the illuminant and extract information about the actual reflectance," neuroscientist Jay Neitz to Wired. Mashable reported that the original picture had been overexposed and some people's eyes overcorrect for that.

At some point, the memes came. Photos of the dress on llamas (the other big Internet news story), users diagraming what colors they saw, GIFs and Vines showing the colors. The list goes on and on. Oh, and Adobe tweeted that a user had used Adobe Photoshop to discover the dress is actually white and gold.

Business Insider found the original poster of the photo, who said she had posted it to Facebook because a friend and her fiance had disagreed about the color. In more photos from the wedding where the dress was worn, it appears to be more clearly blue and black. If that is even the origin of the photo. At this point, who knows what is truth anymore?

P.S.: It's white and gold. Debate over. Or maybe not.
