Knowing GM Paz and his Professor (Lynn Case) I believe they use White, Orange, Purple, Blue, Green, Brown, Student Black, then degrees. As was stated though it doesn't matter as I know they didn't do something like add a Red belt or put Blue before Purple or something like that.
I was talking to Professor Lynn a few weeks ago and am working to get out to Idaho this summer for a seminar with GM Paz, Prof Case, Sif Gary and others. Looking forward to it and hope to meet you Jake.
Cheers,
Tim
