Polemic dress.

Lately, a very strange picture has been going through the social networks and causing problems for its low image quality. The picture consists in a dress that a woman posted with the question: "It's white or blue?". And in less than 24h the world divided itself in 2 social groups: The ones who see it white (like me for example) and the others who see it blue (unfortunately, the rest of my family). Well many people has tried to give a valuable argument about this phenomena but all of them have been destroyed by the others. The interesting thing is that a group of american students has begun a research project about this phenomena and their first impressions look good. They've said that people who has a better night vision see it blue because they don't have a significative colour loss, but people who are not such that good at night vision see it white because they activate low light receptors which make us see things black and white. They have another hypothetic explanation which says that the colour could depend of the contrast with the background, so, people who have a better concentration see it blue, and people who have a more panoramic bvision see it white. I agree with the second theory because it's better for my self esteem :P. I post a photo for you to see the dress.
