5 Years ago today people were divided over "The Dress" specifically what color it was and some are still arguing about it to this day even though we know what the official answer is.
All you heard and saw on your TL was people arguing about whether the dress was BLUE AND BLACK or WHITE AND GOLD.
Before we remind you what it actually was so you don't rehash some old arguments there's a scientific explanation as to why this was so dividing and why people saw different colors.
According to Junkee:
The Dress appears as different colours to different viewers could be due to our brain’s method of processing colour by discounting irrelevant visual information.
Neuroscientists have hypothesised that the colours, strange lighting, and poor quality of the photo have messed with our “chromatic bias of the daylight axis”, causing our monkey brains to alternately dismiss either the cool blue or warm yellow tones of the dress depending on an arbitrary, case-by-case perceptive distinction our minds choose for us.
What’s spooky is that those scientists cannot construct any image to replicate the effect as clearly as it appears in Bleasdale’s photo — The Dress is scientific lightning in a bottle, so of course the internet quickly adopted it as a postmodern mood ring/personality quiz.
The craziest part was that while the majority of people including celebs like Katy Perry and Anna Kendrick saw White and Gold the dress was in fact BLUE AND BLACK according to the woman who posted the original pic of the dress she bought.
