I do shotokan karate and the belt ranking id white, orange, red, yellow, green, purple, purple 2, brown, brown, brown and black for the dans but i have been looking at a lot of site of different styles and i know belt ranking will change but theres a lot of belts with strips on them and most of the moves need to go with them are only half grades? and theres about twice as many belts as of the normal 10 kyu. is this just for younger students or do senoir stundents do this to? is this because there a different styles? other sites the colours are different but the moves need are full grades. please hely me understance
