Here is a list of the five useful colors for negative work. These can be used for candles, mojo bags, etc.
- Red: Hotfoot, Speed, Anger, Violence
- Black: General Curses, Death, Bad Luck
- Purple: Domination, Loss of Power, Addiction
- Yellow: Legal Troubles, Lose Favor, Illness in the Belly
- Green: Sickness, Loss of Money, Rot and Decay
Note: Curses, hexes, jinxes, and other negative spell work should not be undertaken lightly, and are not recommended as they have a tendency to blow back on the person casting the spell.
