It also sends its action message (set by setAction:) to its target object (set by setTarget:), provided that neither the action nor the target is nil. NSColorPanel also sends its action to its target whenever you select a color in the color panel.
Yes, and this is the behavior I want to avoid.
I can turn off the send-to-target behavior easily enough, but I can't turn off the send-a-changeColor:-message behavior.
