The aura is a field of “subtle, luminous radiation” which surrounds a person or object. It is believed that all living things (including humans) and all objects have an aura. Some believe, that with practice (ie: activating the third eye chakra), you may be able to perceive an individual’s aura.
Different colors correspond to different “vibrations” or energies in your auric field. For example, Positivemed.com put together a chart with some of the aura colors and their corresponding meanings…
Turquoise: indicates dynamic quality of being, highly energized personality, capable of projection, influencing other people. People with turquoise strong point in their Aura can do many things simultaneously and are good organizers. They feel bored when forced to concentrate on one thing. People love bosses with turquoise Auras, because such bosses explain their goals and influence their team rather than demand executing their commands.
Green: restful, modifying energy, natural healing ability. All natural healers should have it. People with a green strong point in their Auras are natural healers. The stronger the green Aura, the better the healer. They also love gardening and usually have a “green hand” – anything grows for them. Being in a presence of a person with a strong and green Aura is a very peaceful and restful experience. However, dark shades of green can indicate one who is jealous or uncertain.
Yellow: joy, freedom, non-attachment, freeing or releasing vital forces. People who glow yellow are full of inner joy, very generous, and not attached to anything. Yellow halo around the head: high spiritual development. A signature of a spiritual teacher. Can also indicate mental activity, optimism. It can mean new learning opportunities and wisdom. A golden yellow means that the person takes care of themselves. Ruddy yellow may mean that its owner is shy.
Orange: uplifting and absorbing. Inspiring. A sign of power. Ability and/or desire to controlpeople. When orange becomes a strong point, it usually contributes to a yellow halo, which then becomes gold, indicating not only a spiritual teacher, but someone capable of demonstrating their unique abilities. This is a color of warmth, thoughtfulness, and creativity. The muddier shades may represent pride or vanity, while golden orange denotes self-control. A person with orange in their aura may suffer from kidney ailments.
