Climber3256: I use an adjustable white light head lamp and use the lowest setting for travel in the dark.
I have walked right up on both Moose, Deer and Elk at times (by right up I mean 40 - 50 yards) when they could easily have moved off prior to my getting that close?
I suggest you get a light with adjustable beam brightness - which ever color you choose.
Best of luck with whichever you choose.
