WHICH GREEN?  is about a female standing on green, holding green, and there is green above her.  A choice of the green color was not necessarily one to signify the "natural" or "organic" environment but rather a complementary color to red or dark red in the piece.  In fact, if she is standing on the planet earth and it's grass is green, then what is she holding in her hands?  And why is the star above also bears green as a color of its emanating light?
