This optical illusion can make you see white and black as red and green for 3 months

This optical illusion is a strange one. Unlike "the dress" which made people misperceive the colour of a dress whilst you're looking at it, this one has lasting effects and can make you change the way you see the world.

Be warned, if you look at it for too long it will make you see black and white as green and red for up to three months. Whilst this may be perfect for Christmas, if your work / study relies on you telling the difference between colours you might not want to look at it for too long. If you're an electrician or a bomb disposal expert, you might want to call in sick for a few months, otherwise it could just be fatal, as this video explains...
