@@Daily.Misery.in.a.BOTTLE well there's a white rose that actually can be found in a forest, whoever touched it will die. If that person have a negative emotion, he/she can turn people into an undead by killing them and put a white rose in their head, the reason why the color is red, because that is where their blood went. Green represents us an innocent one and they can't hurt them. And if they have a positive emotion, people can't turn into an undead.
