I use the blue color more as a representation of the earth-body and the solid element. The androgynous is solid, very stable because it is unified. After the ”separation” with the lightning of Zeus, the androgynous became unstable as a man and a woman, looking for each other forever.
Lightning also represents the intellectual though process that divides and analyze constantly and it is usually symbolized as yellow electricity. This is the cause of the ”fall” from paradise, too much thought and too much bodily focus.
Yellow as i described above represents thought, and blue the body, thus the apple is green and not red.
