Lunar Goddess Diana skin

Hi there I just checked out a preview of this skin on youtube.It looks great but the one thing that is wrong with it is the purple? Take a look at the video this guy posted of the skins. http://www.youtube.com/watch?v=HSNhkQ3I1hw. Just before it shows the actual skin it has artwork of the new skin in silver gold and black which not only looks dam sexy the colors make more sense than the purple. Black for the night pale gold for the moon and silver for moonlight. I just don't understand why they would use purple when the other 3 colors look so much better and make more sense.... to me anyway.
