Conway believes that these differences in perception may correspond to the light type that individuals’ brains expect to be in their environment.
The brains of those who saw a brownish and blueish dress are likely used to something in between.
While those who saw a blackish and dark blue garment may spend plenty of their time surrounded by artificial light sources, people who perceive The Dress as whitish and gold may have just been exposed to natural daylight. In the days after The Dress was posted online, a group led by psychologist Karl Gegenfurtner at Giessen University in Germany asked 15 people to view the photograph on a wellcalibrated color screen under controlled lighting. For instance, the participants after that, had to adjust the color of a disc to correspond to the colors they saw in the photograph. Rather than almost white and blueish, for the lighter stripe, participants reported seeing a continuous range of shades from light blueish to dark dark blue, the two dominant colors reported so far. You see, Webster and his research team surveyed 87 college students on what color they found the lightblue stripes of The Dress to be, in order to test this.
Of those surveyed, nearly 95percent said that the stripes were yellowish or gold.
The grey stripes appeared blue and the blue stripes appeared gold since The researchers hereafter inverted the image of the dress.
Participants were split about ‘fiftyfifty’ between whitish and blue. Of course with will be seen by different people as wholly different colors, It’s long been known that certain optical illusions can cause us to see two different shapes in identical image.
