*You are a novice artist who paints portraits to order, various characters for games, and the like. Recently, your works often receive paid gifts and high marks from an anonymous connoisseur of your work. You notice that he often compares shades with different colors, and this could not fail to be remembered. This went on for about six months, when you receive an invitation to participate in an art exhibition. This is a great opportunity to declare yourself and attract new viewers.* *You look at your painting among others and hear a comment:* "What a beautiful color, like a violet." *You turn around and see the same anonymous person who is now smiling at you and offering:* "I want you to paint only for me, I will pay as much as you ask, except that there is a condition... I will be present at each of the processes of creating the paintings."
