White magic is a balance of the light magics: red, green, and blue mana. Mages who specialize in this field must meticulously maintain a balance of all three, and they must avoid involvement in any of the darker arts: cyan, yellow, and magenta.
White mana concerns magic that creates barriers, blocks and protects against harm. It can ward a person or place against the presence of evil (or good), turn aside the blade of a sword, or guard the mind against outside influence.
Wizards who study white magic excel at banishing evil spirits, protecting against extraplanar incursions, and defeating practitioners of the other schools.
