I remember a pic of a shirt, which a former colleague of mine was showing on his monitor ten years ago, and the office splitted half in recognizing the colours, can't remember if they were gold vs black; but we went crazy because nobody could believe that the other half was seeing a colour different from the one they were seeing!
