I wouldn't get one unless I was a black belt, even then I probably wouldn't get one.
There is so much that can happen between white and black. I was gung ho for my original school until the past few years where they've gone totally mcdojo and I would NEVER want to be associated with them.
So I guess if you choose a bjj tattoo stay away from your association.
I like the idea of a tattoo about BJJ, but not BJJ itself...like Telles, who has a octopus, which relates to BJJ well with it squeezing the life out of it's prey and all..something like that is more meaningful and cool to me.
I have been considering an octopus for a few months now. The Blue ringed octopus.
I am little guy, I have a complex
"The blue-ringed octopus is the size of a golf ball, but its venom is powerful enough to kill humans. There is no known antidote." "Despite its small size, the blue-ringed octopus carries enough poison to kill 26 adult humans within minutes."
