Green is the tone related with the heart chakra, so it connects with issues of the heart: love for you and others, sympathy, and pardon.

If this is your case and you have green in your aura, you likely love music, nature, and being free. Since a green aura shows an especially open heart, there might be a propensity to be easily influenced by one's current circumstance or other people's, making limits is significant for this colour.
