"The Dress" took Twitter by storm in 2015. So much so that it got it's own Wikipedia page.
Since then there's been several "What color is this?" pics, but none, in my opinion, as compelling as "The Shoe." Some say Grey & Mint while others claim Pink & White.
I honestly thought it was Grey & Mint until someone showed me the color corrected photo and now all I can see is Pink & White. It's kind of disappointing. There is an actual reason we can see the exact same photos differently. You can read about it here or just suffice it to say our brains are strange and don't always interpret things correctly.
