Bit bulky. Two heads, one on each side of the battery tube may be a better option.
I’m not sure hunters need or even want 3 colors.

White:
Scares away animals.
Impairs night vision.

Red:
Doesn’t impair night vision.(tail lights of cars)

Blue:
Spot blood,
Ideal for (map) reading because it give superior contrast to black on white.

Green:
Can’t be seen from the side.
Doesn’t scare animals.
It’s even claimed it attracks deer.
The human eye is most sensitive to this color, so can see at lower lumen.
More contrast and sharpness.
Doesn’t impair night vision

So in my opinion a hunters flashlight only needs green and blue.
White is the worse choice of all.
If I had to pick just one color it would be green.
