Blue LEDs are useful for pilots and other personnel who need to read maps at night. Other colored LEDs (such as red LEDs) will not work for map reading because it will wash out red lines. Blue LEDs are also used by police and crime scene investigators because it will make blood and bodily fluids visible that are usually invisible to the naked eye. Blue light is the only light that can cut through fog, which is why it is widely used for fog headlights.
Green LEDs are useful outdoors. Many hunters claim that the green light attracts deer and other wild game, and the green light will not scare away fish, deer, and other game like a bright white light will. The green LEDs also have a longer run time than many other colored LEDs.
