    green works better than red for reading, no doubt…

    green works better than red for seeing anything: trees, trails, animals, maps, compass…

    there are trade offs…

    green attracts more mosquitoes than red

    green interferes with sleep hormones, red does not

    the argument that green can be dimmer than red is true, but green is not politically correct for group stargazing, Red is Required

        yes, green has become more popular with the military also, but its not because it is more stealthy… Night vision equipment uses red light sensors, and it over reacts to red lights. otoh, Night vision equipment does not have a problem with Green lights.

        Submarines use Red Light to maintain Dark Adapted vision in case crew needs to look through the periscope into the dark of night.
