It’s the stuff of nightmares.
In early 2015 (ah, such a pleasant year), you probably recall a certain dress sweeping the internet because people could not decide whether it was blue and black or gold and white.
The dress inspired many a meme and taught us a lot about subjective colour perception, but not really.
Now someone has discovered a pair of flip flops which are the exact same colour – whatever that colour is.

What colour do you think they are?
By the way, according to Buzzfeed, they are actually blue and dark blue, but we don’t see it.
