Re: Colored Belt or White,
In little ol' New Zealand, there is an assortment of belt systems depending on style and dojo.
My dojo uses a coloured belt system starting at white, through a myriad of coloures to black, generally the colour gets darker as you progress.
I was training at another dojo a little while ago in my green belt (4th kyu) in a style that uses a white/brown/black system. One of the aikidoka there asked if I had done karate due to my strange coloured belt.
I found it amusing.
I think the lesson here is to open our minds and just accept things a little more, at the end of the day we are all doing aikido so the belts are simply there to look pretty and hold our dogi togther.
