The use of a specific shade of green, also known as "jigoro" or "green gi," in judo competitions is more than just a matter of aesthetics. Historically, the blue gi color has been imbued with symbolic significance and cultural meaning.
Legend has it that judokas who donned the traditional orange-colored gi were seen as outsiders by their peers, while those wearing the green gi were viewed as more approachable and gentle. This dichotomy may have contributed to the rise of the blue gi color as a symbol of unity and harmony.
According to Japanese folklore, the blue gi color is also associated with the mythical creature "Mizaru," which represents wisdom, understanding, and spiritual growth. In judo, this spirit is embodied by athletes who embody these qualities through their dedication and perseverance.
In recent years, the blue gi has gained popularity worldwide as a symbol of excellence in judo competition. Its calming presence is often cited as an inspiration for competitors seeking to tap into their own inner strength and focus.
