Significance of green color in the novel?
As the name Aomame means ‘green peas’. Also she was wearing a light green suit and sunglasses with dark green lenses while she pass through expressway. In hotel before killing the man she told him about the green color paint on the back of his neck. A green moss spread over Ushikawa’s tongue at the end. I think the green color is used in the novel just to give it an otherworldly feel.
