“This is crazy! These shoes are clearly green and grey. My husband sees pink and white,” one confused person declared.
“Pink and white. Can’t imagine anyone seeing green,” another wrote.
"Clearly green. How do you see anything vaguely like pink?," said another.
“My eyeballs are ready to fall out my head from staring so hard trying to figure out how anyone could see pink and white here. It’s so clearly grey and vibrant mint coloured green. This is crazy,” one said.
Some even said the shoes appeared to change colour, the more you looked at them.
“First glance I saw pink and white, scrolled down to read comments and went back to the top. The shoe is now teal and grey! What is this sorcery?”
