I don`t think I have any need to say why I choose her to be Melisandre. Red hair, red eyes, red lips, young and splendid like the real Melisandre from the books and just red, but red like fire. With a red necklace at her neck (obvious) and all dressed in red flames. If there is the Lord of light than she is the Lady of fire. Not even Melisandre could disagree with this.
