Indigo is a color that many of us would call navy blue. It is related to the third eye, or brow chakra and affects intuition, enhances a sense of responsibility and has a calming, sedative affect.
Ajna (along with Bindu, is also known as the third eye chakra) is linked to the pineal gland which may inform a model of its envisioning. The pineal gland is a light sensitive gland that produces the hormone melatonin which regulates sleep and waking up. Ajna is symbolised by a lotus with two petals, and corresponds to the colour white, indigo or deep blue. Ajna’s key issues involve balancing the higher & lower selves and trusting inner guidance. Ajna’s inner aspect relates to the access of intuition. Emotionally, Ajna deals with clarity on an intuitive level.
Because of its sedative affect, indigo is not usually a good choice for rooms where there needs to be activity. It works quite well in quiet areas, though, particularly bedrooms or studies.
Too much indigo can cause a feeling of loneliness or depression. Use orange to balance these affects.
