History

The roots of magic come from the Celts, a people living between 700 BC and 100 AD. Magic can affect many outcomes, some good and some evil, depending on the type of magic and the intentions of the practitioner. It was also practiced in ancient Egypt and then in Babylon by the pagans. The more well-known types of magic are denoted by colors
“"Black magic" is performed with the intention of harming another being, either as a means of building the practitioner's power or as the goal itself. The underlying ideology upon which black magic is based states that the practitioner and his or her pursuit of knowledge and/or physical well-being are more important than other concerns, theological or ethical.
"Green magic" involves the practitioner's attuning himself or herself to nature and the world around him or her.
"White magic" is where the practitioner attunes him or herself to the needs of human society and attempts to meet those needs. This is a form of "personal betterment" magic, and does not entail harming other beings.
"Grey magic" is magic that is neither green, nor black, nor white, and which usually replaces the absolute stand of these realms with an ethical code that is particular to the practitioner. It is a type of magic all its own, and may be used for many different purposes.
"Folk magic" is an eclectic collection of Herbalism, faith healing, curses and hexes, candle magic, and other workings that has thrived in rural areas for centuries. There is also the term, "hedge wizard," which refers to an individual who attempts to practice magic with little or no formal training”. (History of Witchcraft and Magic)
