It's the bloody dress all over again.
Playing on the internet's apparent obsession with 'things that look like things that they actually aren't', the team of Bite Size Psych have created an optical illusion sure to befuddle your poor old eyeballs: what appear to be several rows of purple and yellow hearts are actually all a single shade of pink. Bonkers, eh?
Yes, both of those hearts above are the same colour.
But don't fetch your burning torch and ring the witch bell just yet.
Mercifully, unlike the famed blue and black/gold and white dress, this illusion is provided with a full explanation of why your eyes are fooling you.
From an insight into how your sight works, pull up a chair and watch the below.
