Most of the time they appear white to the human eye, taking a photo would show them as bright green or red. This was filmed in color, but set on night shot." NASA: The Mystery of the Aurora I'm not an expert in this area...I just do research on their effects on humans. Hope this helps some. Is there some simple explanation why they appear white to naked eye while they're brightly coloured in photos? And could you tell us what have you found, ho... [More]
