Pcurrent, that's a bit different from what I learned when I was in.
We learned that Red is better for preserving night vision, although your color ability is almost nil in it.
Blue, while allowing some color, has a tendency to "disappear" when you are looking at it at night. Now you see it, now you don't. Unfortunately, with NVG's, you'll see both from quite a ways away.
