Star children are divided into three categories: Indigo, Crystal and Rainbow. If you are a star child, regardless of which category you fall into, star children are known to embody the energy of grace, purity, truth and wisdom. They know that all life on Earth is sacred and should be respected, and they seek to rebuild the Earth by spreading compassion. Indigo, Crystal and Rainbow have a lot in common, but they are also different personalities that stand on their own.
