Last night, the Internet was sent into a frenzy by a dress that boasts just two colors. A photo of a dress went viral on Thursday night because people are having difficulty agreeing on what the two colors are: white and gold, or black and blue.

Sarah Weichel, a talent manager whose roster includes Youtube stars, told Business Insider that the dress is “Black and blue of course!”

According to BI, “21-year-old singer named Caitlin McNeill who lives on the tiny Scottish island of Colonsay,” posted a photo of the dress to Weichel’s Tumblr fan page and from there, it hit viral status.

I thought my followers on Tumblr would maybe have a good reaction, but I never would have considered that Taylor Swift and Mindy Kaling would be tweeting about it,” McNeill told BI.

She said the dress was worn by the mother of the bride at a friend’s wedding and in person, nobody disagreed on the colors: They were black and blue.
