We got red filters for our torches in the army, since for obvious reasons soldiers would rather not show a light and try to preserve their night vision. BUT under a red light; red lines on the map aren't visible. I went for red for my own use. There aren't many red things in the woods I'll be worse off for missing. A lot of green things.
