Are Ritual's considered black or white magick?

[[email protected]]

Maybe they're not considered either, but I just wanna know for sure. I've been using one of my Satanic Rosaries to count and keep track of the number of times I vibrate the Ritual, especially in the Serpent Empowerment ritual since it has to be vibrated 18 times, along with the affirmations. I remember reading on the Satanic Rosary page that one rosary should be used for white magick and a separate one for black magick, so as to prevent cancellation of the energies. Should I use my "Ritual rosary" for black magick or white magick, or does it not apply in this situation?
Also, follow up question: is it harmful to wear a black magick Satanic Rosary? I often wear my Ritual rosary under my shirt so the Christians that I live with won't find it and throw it away or something. Of course, here I'm assuming that Ritual's are in fact black magick, but I just wanna make sure that what I'm doing won't harm me.
