The original belt system of the Gracie Jiu Jitsu was white belt, light blue for instructor and darker blue belt for the head instructor. The belt system that the IBJJF currently used was created by Helio in 1967. Later in his life, Helio decided to wear his dark blue belt again as a form of protest of the current changes of Jiu Jitsu becoming a sport and other things. Apparently, Helio never wore a black belt or a coral and went from dark blue straight to red belt.
