Red has been used for years to preserve night vision for a reason. More recently there is discussion in some circles that other colors do just as well to preserve night vision. I speculate that it is the proliferation of Night Vision equipment and images in the media. After reading various sources, my conclusion is that Red is the best for maintaining night vision, but it may not be so good for reading charts at night. Keeping the red light as dim as practical will also help NV.
is a pretty good discussion of the subject.
