Technology behind night vision, why is it green?

Why is the image color of the night vision device green? If you think it's because green, according to popular theory, is preferred by geniuses, you're mistaken.

The main reason is that the image intensification screen inside the device is made of phosphor. This substance is used because of its luminance effect, and when struck by electrons that don’t carry color information, it glows bright green. As the electrons pass through the tube, they flow through a microchannel plate, a disc with millions of microchannels. Striking these microchannels bursts of voltage causes the motion to increase rapidly, forming dense clouds of electrons that intensify the original image. These same electrons then strike a screen coated w / phosphor at the end of the tube. The energy from these electrons creates the greenish image on the screen inside the device. Green phosphor is used because the human eye is most sensitive to the green color pallet and distinguishes more shades of green than any other color.
