The problem is, is that most of the higher ups know. When you are a priest you are in the dark and only where a white color, the yellow is introduced into the regalia to signify happiness, then red is introduced slowly, indicating blood, until you are fully red, then the pope dresses in white because they want to signify purity and all that red is washed away. Like the priest at Bush's funeral said, "It is about the family" as an excuse for their crimes in order to live a good life, and not about yours.
The Jews are the opposite, they start with white caps, until black, then that cap grow taller and taller, signifying the darkness of their order and how you grow into it.
