I have been a student of Martial arts for over 6 years now and have attained the rank of 2nd Black in Tae Kwon Do and 1st Black in American Kickboxing. I started instructing begineer levels when I was a 1st brown in TKD. The belt system for TKD in my school is: (White to brown have 1st and 2nd levels, Black has 9 levels) White-Yellow-Green-Blue-Red-Brown-Black Kickboxing has only one level of each but follows the same color system.
