Red filter – The Red filter is great for penetrating fog and smoke, and ideal for signaling. Red is also ideal when you want to preserve your night vision. Hunters use the red filter to avoid disturbing animals during pre-dawn hours — animals see poorly in the red color spectrum. The filter is also useful for close range, non-tactical applications — such as map reading — as it reduces the intensity of light output.

Green Filter useful for map reading, hunting to avoid spooking game, tactical applications, blue provides a little more light for easier viewing or navigation over red filters.
