Sneaker debate is back: Pink/white? Grey/Teal?

(CNN) Here we go again.

Sneakers are once again at the center of a debate over who is right. Social media is going crazy over the color of these shoes.

The singer Lizzo posted, “I see grey and teal but my whole team sees pink and white, help.”

Actor Will Smith also chimed into the conversation by posting a video to Instagram.

The debate about the color of these shoes has been goin on since they were first posted online in 2017.

And before that, the dress debate took over the internet in 2015.
