What would be the word for something that is opposite its appearance? Let me give you an example. Say there is a button that can be pushed which would instantly destroy most of civilization. Let's say that this button was decorated with a picture of a smiley face, or a kitten, or something equally "opposite".
What would be the word for the fact that the button, which would destroy the world, was adorned with the picture of a cute, innocent, kitty cat?
