Very interesting reading regarding this subject:
Night Vision - The Red Myth One of the statements in this article says: "
Note: The red filtered light at the intensity most people use is likely decreasing night vision much more than a properly dimmed white or blue-green light would!" which is exactly what I have been observing on myself in decades of amateur astronomy and night flying.
NB: Jeppesen Mobile Flight Deck does also have a night mode which is not red (just like the cockpit lighting in most modern aircraft is not red either)
