A new picture has just surfaced on the internet of a slippers which appears to be creating a lot of contoversies over its colour. This is just another optical illusion that plays with the minds of the viewer. This is not the firt time that such an image would be causing a lot of confusion. The image was first posted by a Portuguese Twitter user who asked what colour they were, the image has been shared thousands of times with many at loggerheads over what colours they actually are. Some argued that they saw blue and black, others claimed to see white and gold, while some insisting they saw blue and brown. Fellow Naijaloadites what colour can you see. As for me I can see blue and black.
