When presenting designs to clients some firms add a "pink rabbit" to it, i.e. something that's just too obvious to be ignored by the client. The discussion will then be steered to what to do about it, how to change it, what color it should have, etc.

This is a way of deflecting the client's need to "contribute". If there are other issues with the design those will come up as well, but that initial itch will be lessened.
