On all U.S. Navy warships, not just submarines, lights in passageways are changed to red after dark for exactly the reason alluded to - so that topside watches will be adjusted to night conditions.
This is speculation. Rig for red means Q is getting ready to surface.
It refers to a submarine when it prepares to surface. Specifically Q is still completely underwater but a periscope alone comes out of the water and Q get visual information on usually a target such as a ship, or coastline in the event we are looking to gather intelligence or launch an attack.
"Rig for Red" is normally a command used in the Control Room. It is normally used when the boat is going to be surfacing or coming to Periscope Depth at night. The purpose is to give the lookouts and the officer designated to head to the bridge upon surfacing a chance for their eyes to adjust to darkness, or the OOD the same thing before looking through the Periscope.
