I didn't say that a yellow topped rotor was banned, I just said that it wasn't a good idea. Paint from our vendors and will be yellow mainly (perhaps still some orange). It's just a case of logic, if you have a bit of yellow somewhere, you might inadvertently get pulled by a ref thinking its a hit. It's common sense at the end of the day, these are merely guidelines designed to help the players. If you do have some yellow on some kit, just make the refs aware of it so it doesn't end up ruining you game.
