Does anyone happen to know the significance or meaning of the black vs. indigo or even brown or grey hakama? Did they used to represent different clans? regions? particular martial art background?
also, a little off-topic. I have a black hapkido gi and and planning to start formal aikido training in a few weeks. I know my current gi is durable enough for aikido, but is it totally untraditional and unacceptable to use in an aikido dojo? I understand I should ask my sensei for the final decision, but I just thought I might eliminate an option right now after hearing from some people.
