The debate was later resolved with an explanation of color constancy, but in the end, it remained a hot meme and point of dissent for many.
Now, it looks like there's a new optical illusion that's stirring up conversation on the Internet. Instagram user Hunter Culverhouse posted a photo of legs covered in white paint, but some people are seeing shiny, glossy legs instead.
Culverhouse told Insider's Jacob Shamsian that the illusion was created on accident.
" [I] had some white paint left on my brush and put random lines on my legs, turned out to be a completely confusing picture for everyone on the internet."
What do you think? Shiny legs or legs with white paint?
