In many martial arts, black belts are often worn for all "dan" grades. In others, different colours are used with sometimes the highest grade (10th "dan") wearing in some systems a red colored belt. In Jūdo, 6th to 8th "dan" may wear a red and white-patterned belt and 9th to 10th "dan" may wear a solid red belt. Blue with a red stripe is sometimes worn for Renshi (錬士) or for a person recognized by the older Ryu Kyu Kingdom title of Shinshi (from Shenshi, 紳士), a general Confucian term for a resident Chinese scholar and emissary. There is some variation even within styles. Generally, belts do not have markings that indicate the actual "dan" grade. Okinawan styles often use gold bars to denote the various masters titles rather than grades after fifth "dan". Thus one gold stripe can designate , two designated , and three designated . In the early 2000s, different Okinawan styles started using the stripes to designate individual "dan" grades above "godan". Others, including many Uechi organizations, have followed suit, while others have not.
