It should put the red lense flashlight If you want to avoid detection in the night?

I know that red has the longest wavelength and lowest frequency. But I'm looking for little more than information. Light purple is a good? PS Why or why. I'm not looking to rob banks or anything like. Just a question because I have white and light red. my keychain and I have noticed a difference in the night.

Eye sight has two basic types of light other. Cells: cone cells for detection of color and good detail, but have a fair amount of light in the cell cars that run and not be found, but the color is light. You owe the most. The ability to see the night of your cell vehicles, but these cells blind to red light. Red light must therefore relatively bright eyes for it. Although this is dull red. Low power to see the distance to avoid detection is not the main purpose of the red lens. This lens allows you to open your flashlight to read not temporary. messing up your night vision. So you will use a red lens flashlight to read the settings of your camera and save them as astronomical observations. Purple with a blue section. Cell vehicles is just important for this purpose will not work nearly as.
