After reading this question about Big Bad Red buttons, where it was generally agreed upon that red buttons draw the user to click, I was left thinking: then when are they good affordance and interaction design?
Red buttons usually mean something negative, so I suppose users will be expecting that of a red button.
Red buttons draw users to click instead of avert from it.
The two statements above seem to work against each other. So is the red color "out" for buttons? When is it a good idea to use it, if at all?
