The order of belts in karate varies depending on the style, school, and country. However, the most common belt colors used in karate are white, yellow, orange, green, blue, brown, and black. Here is a list of the most common karate ranking, the 6 kyu system:

• White Belt
• Yellow Belt
• Orange Belt
• Green Belt
• Blue Belt
• Brown Belt

Some karate styles utilize 8, 9, 10, and even 12 kyu systems. Its important to note that there is no standard regarding karate belt colors as it varies with schools and organizations.

In addition to the belt colors, some schools use stripes on belts to indicate progress towards the next belt rank. For example, one schools stripe requirements are: yellow for techniques set #1, orange for Judo, blue for techniques set #2, green for katas/forms, red for techniques set #3, and brown for Jiu-Jitsu.

Its worth noting that the belt system is a relatively new component of karate, borrowed from Judos kyu/dan system. The black belt was designed as a way to show competence in the art, not mastery of it. The black belt is only the beginning of the journey.
