Auras are believed to be the unique energy field surrounding all living things, and though most people can't see them with the naked eye, every aura is a different color or combination of colors, with different meanings behind them.
Blue: Helpful, caring, spiritual, intuitive, generally at peace and content, understanding, peacemaker, steadfast, freethinker. Some believe that problems a person with this aura color may experience are related to the throat or thyroid.
Spiritually: Represents meanings of depth, trust, loyalty, sincerity, wisdom, confidence, stability, faith, heaven, and intelligence. The color blue has positive effects on the mind and the body. The color blue in many cultures is significant in religious beliefs, brings peace, or is believed to keep the bad spirits away.
