Green
Green is the color of his tormented soul. It encompasses all his emotions. Green is his color, but the extremes of feeling aren't. The color of grass, the color of life, his dancing on the edge of insanity. Emeralds dance behind his lids, but they are for only one creature. She can claim his soul, his grass-shaded soul, and his eyes are for only her. If she were to ask, he would wrench them out and gift them to her. But she doesn't realize the depth of his emerald soul, so the spirit of the gift would be in vain.
