Posting the picture in a group on Facebook she wrote: "Ok girls so my friend has just sent me this asking what colour the shoe is, I would say pale pink and white, but she insists its pale blue and grey."

The picture is now dividing the internet with a split of colour perception.

Last year a similar opticial illusion of a striped dress divided the internet for weeks whether it was blue and black or white and gold. 

So... what colour is the shoe?
