I have probably painted a target on my back now. Let's get over what belt color is associated with what guep.
Funny thing is, I actually did find the answer, in the 1992 and 1999 Taekwondo Handbook published by the WTF, which lays out the belt colors and the associated guep rank. Back in 1992 and 1999, the WTF still had its offices at the Kukkiwon, and for all intents and purposes, everything was united under Dr. Kim, who was president of both. So what the WTF had written about it, was the Kukkiwon color belt system at that time, since there was no dispute then that Kukkiwon was the sole authority and word on promotions, belts and that area of responsibility for Taekwondo. The belt system was also mentioned in the 1986 and 1988 versions of the Handbook, and I have a 1972 KTA pamphlet that also talks about color belts. It's all over the place.
But you are right, let's get over it.
