Yes yellow is better than white
I suggest not gettin White or black. Why? White will make a contrast to the colour of your teeth to the pure White braces. If you have yellow teeth, they will look worse than before. And Black braces do the same thing. If you have yellow teeth, it's gonna make it look like you chewed up a bumble bee. But of course, if your teeth are pure White, any colour works pleasurably:)

It depends on the application and requirements.
your teeth being white or not has nothing to do with your skin color, i can be white and have different color teeth, so just because your black doesn't mean you have white teeth. think about it. Well the final answer is no. anyone can have white teeth
