Is this girl's hair purple, blue or pink?

A few months ago, social media users were obsessing over ‘The Dress’ and whether it was white and gold or black and blue. Now, it is ‘The Hair’.

When 24-year-old Sabrina Abu-Obeid, a resident of Florida, US, dyed her hair, she didn’t think she would become the talk of the town.

A video of her went viral on the internet as people noticed that the purple shade of her hair looked quite different depending on the lighting. Within two weeks, the video had over 2.5 million views on YouTube alone.
