Before the invention of Martial Arts color belts was not simply a white belt and a black belt and nothing in between. It was not unusual for the disciple of a teacher to study for years while wearing a Martial arts white belt until one day nothing, the student teacher received a black belt and that was it. The common myth to begin with a white belt that gradually gets dirtier the train longer and eventually becomes black and then over a long period of time fades again and becomes a dark gray, the designation of advanced range is nothing more than that a myth!
