In Tibetan culture, and some others, green is considered to include all the other colors.

Green Tara is typically pictured as a dark, green-skinned girl of 16.  She usually wears striped leggings but above, only her shoulders are covered.  She wears the many characteristic ornaments of the samboghakya.

Green Tara has her right foot extended as if about to rise. Her left hand, in the gesture of granting refuge holds the stem of a blue water lily or utpala that waves over her left shoulder while her right hand also holding a flower, offers that which we desire, a boon.

 According to the first Dalai Lama (1391-1474,) her hands with their blue utpalas signal, "Samsaric beings! Cling not to worldly pleasures.  Enter the great city of liberation!  Flower-goads prodding us to effort.  Homage to you!"          

The practice of Green Tara helps to overcome fear and anxiety, but devotees also believe that she can grant wishes, eliminate suffering of all kinds and bring happiness. 

 When called upon, she instantaneously saves us from eight specific calamities.  (Another lineage describes 16.) The First Dalai Lama lists the 8, and interprets them as representative of corresponding defects, flaws, or obscurations: 

1) lions and pride
2) wild elephants and delusions
3) forest fires and hatred
4) snakes  and envy
5) robbers and fanatical views
6) prisons and avarice
7) floods  and lust
8) demons and doubt
