A bright ring or circle of light typically hovering above or traditionally behind the head that either symbolizes purity or to denote that the character is an angel or saint. This tag applies to all kinds of halos which hover over one's head, not just those that are considered traditional - for such halos only, see traditional halo.
Not to be confused with the optical phenomenon caused by ice crystals in the atmosphere surrounding the sun or moon, forming a halo, or halo-like artifacts of light caused by bright light sources interacting with the camera lens. The latter is a lens flare.
