In the 2.4 patch notes, there is a mention of later adding colored bows into the game. I can understand why, there can be only so much variation in the archer design before it becomes repetitive. Also it allows future archers to stand out from the previous year characters. Making legendary bows like Yewfelle, Double Bow, and Rienfleche not complete directly against BLyn's Mulagir I wonder what will determine the color of certain heroes, and then Noire can be in the game?
