'The Dress' debacle that went viral earlier this year and split friends and families over the colour of its stripes, has sparked a fresh debate among scientists.
Apparently, women and older people were more likely to see the dress as white and gold. However, it's now thought that the same group are more likely to be early risers as opposed to night owls.
The theory goes that people who stay up later have more experience of artificial lighting which has more reddish light in it. Their brains may then be accustomed to correcting from reddish illumination. Take these colours out of the dress image, and it appears blue and black.
On the other side, people who are awake in daylight hours are exposed to more natural light, which contains more blueish light than artificial light. If the brain assumed the dress was illuminated by more natural sunlight, and corrected for blueish illumination, the colours appear more white and gold.
Did you see blue and black? Are you a night owl?
