What do the different colors of magic mean then?

Modern practitioners gave different forms of magick different names. White magick suppose healing and everything 'good'. Red magick about love blah blah blah. Green magick about nature and herbalism. Black magick about communication with spirits and darker practices. But in all of these categories there is one person willing to abuse of the capability of the magick. That's why I'm not going with the whole black and white magick being good and evil. It's like some people see angel ouija boards. They suddenly think it's a positive thing. It has the same effects as any ouija board if you're not aware of what you're doing.

White magick deals with everything good and black deals with darker practices... That sounds like black is still bad and white is still good...

Why is communicating with spirits in the black magick grouping, that makes no sense?

Is it always in group? Necromancy is an act of 'black' magick yet even Jesus performed necromancy. Does that make sense. Kinda like belief racism don't you think?

Okay, I know black isn't necessarily always bad. So I'll just use the terms good and bad magick instead of black and white. Lol it is belief racism.
