Red helps to preserve night vision, yes, but a bright enough light of any wavelength is going to kill night vision. . . . .
There are several reasons for using Red for hunting, but if you're interested in not spooking the animal, the Red is best because they have no sensitivity to Red - only Green and Blue.
You need to make sure the Red light is bright enough on the Target to trigger the Cones in Photopic vision, because human starlight-level (Scotopic) vision is also insensitive to Red.
