The photo originated from a washed - out colour photograph of a dress posted on the social networking service Tumblr. In the first week after the surfacing of the image alone, more than 10 million tweets mentioned the dress, using hashtags such as # thedress, # whiteandgold, and # blackandblue. Although the actual colour was eventually confirmed as blue and black, the image prompted discussions, with users discussing their opinions on the colour and why they perceived the dress as a certain colour. Members of the scientific community began to investigate the photo for fresh insights into human colour vision.
