Blue filters are often used when reading maps or other writing because they cast black lines in stark relief against white paper. If you are on an overnight hike or mission, a blue filter will certainly help to keep you on the right path.
One of the additional uses of blue filters is for hunters. Tracking wounded animals at night means picking up a blood trail. The blue light helps the blood stand out against foliage.
In many situations it pays to have colour filter options – especially when you want to see but not be seen.
