INCORRECT.
Harry also wears black, that being the standard color of Hogwarts uniforms.
But Harry doesn't wear all black, there's at least some other colors to his outfit.
Especially in the movies. As the kids aged, they did away with the robes in favor of making them look as fashionable as possible.
You could almost add Solomon Kane (Robert E. Howard's creation) to the diagrams, my best guess would be along with Batman, unless there are supernatural powers I do not know about. I just found and watching it on Movies On Demand, before it got on theaters. 9.99 is a steep price for it, but so far, it is looking OK. If there's anything remotely PC in that movie, the Solomon Kane movie will probably tank in the theaters if it gets there. Rated R instead of MA, so that's strike one.
