Red doesn't hurt night vision like green and blue do, and allows the eyes to adjust.

As to the garage door functioning as an emergency exit... it's easy to operate them without power (pull the red cord and yank up on the door!), but clearly don't have panic bars and might not function terribly well in an actual fire with that respect.

Actually, would be fairly easy to set the spring tension on the garage door for negative pressure- EG, the door naturally will open by itself, and the opener has to work to push it DOWN. But this would still require people to think clearly and be able to work up high in the room.
