Perhaps I'm just used to the 'inverse-video' effect on GNU/Linux, but 
that monochrome effect (having black and white switch places on two 
lines of the frame) is both noticeable but not alarming.

The cursor itself will be a mild disturbance, the colorful flash at the 
bottom should be a tad more jarring.

I'm not sure if red is a good choice, though. After all, the action we 
just performed (abort/quit) does not necessarily imply any kind of error.

I'm comparing to the (setq visible-bell t) behavior on GNU/Linux.
