Fine the way it is. As to the ones you listed, "Rainbow in the Dark," seriously? That's hardly a puzzle. All you freaking do is keep stepping on the buttons until each is the right color, stepping on one doesn't affect any of the others. That's not a puzzle, its just a password entry device. You don't need someone puzzle genius for this, if you're in a group that doesn't have one person who knows how the color code is, you're most likely playing with people who have never ran the quest before. Two, if this is the case and know one knows it, look it up. Messing with it first changes nothing, and it will hardly take any time either way. Once again, its not a puzzle, its a question, which you then provide the answer for.
