You are just naming colours.
What does it MEAN to have a specific type of aura?

So. We've got:
>Goetic magic: achieves things by using violent compulsion on spirits
>Sympathetic magic: affect anything by affecting an effigy of it (or a related method)
>Astrological magic: utilises timing and ritual in order to harness cosmic forces
>Theurgic magic: petition a deity to get something done for you
>Energy work: you cultivate your own energies in order to accomplish tasks occultly but manually
Am I missing anything? Or are these all the methods available?
