if a school Does have a colored belt system and somebody decided they want to wear their white belt I feel it is a pretension of humility and I find this type of person extremely arrogant and inconsiderate in their partnering, in general.
That would be me, apparently, although I perceived my pretension of humility and arrogance as politeness.
Due to belonging to an independent dojo, my rank, though attained legitimately, is unregistered with anyone and the only proof of it is in mind and body.
I usually wore a white belt whenever visiting other dojo until I reached black, even though we wore various colors in my home dojo. Now I still carry a white belt and when it seems appropriate still ask at new dojo what I should wear before getting on the mat.
