Are game animals such as deer and wild pigs able to perceive red light?
Answer From the research I have read, it seems well known that most mammals operate within the visible light range, like people. However, that doesn’t mean that the colors they perceive are the same as ours. For example, a deer or pig may not perceive “red” the same way we would, like a color blind person. Nevertheless, the wavelength of light that represents red would still illuminate the surrounding area and they could “see,” i.e., seeing in the dark should a red light be used. Therefore, there is the possibility that game animals could become startled if a red light was flashed their way in the dark – not necessary because the light is red but because of the “light” it produces. For us humans, we often use red light at night to see with because that particular wavelength is different than direct sunlight. During the day, light constricts our pupils when we are outdoors. At night our pupils are dilated. The red light causes much less constriction and still illuminates the surrounding
