In Buddhism, green is in the middle of the visible, seven-color spectrum and thus epitomizes the qualities of balance and harmony. It is the color people relate to in nature, trees and plants.
Green Tara represents a blending of white, yellow, and blue - colors which symbolize, respectively, the functions of pacifying, increasing, and destroying.
Green also denotes youthful vigor and activity, and the Green Tara is always shown as a young girl having a mischievous and playful nature.
The Buddhist Lord of karma (action), Amoghasiddhi, is also associated with this color, reiterating that green in Buddhist thought is the color of action.Source
