True or False: Supplemental lighting for night vision goggles must only be red or green.

Supplemental lighting used with night vision goggles (NVGs) is designed to enhance visibility without overwhelming the sensors of the NVGs. While red and green lights are often used because they are less likely to cause glare or wash out the images seen through the goggles, they are not the only options available. In many cases, other wavelengths of light can also be utilized, including near-infrared lighting, which is optimal for NVGs as it is largely invisible to the naked eye yet can be detected by the goggles. This allows for greater flexibility in different environments and situations.

Using solely red or green lighting would unnecessarily limit the effectiveness of NVGs. Therefore, it is essential to understand that while red and green lighting can be beneficial, the statement that supplemental lighting must only be of those colors is inaccurate. Thus, the answer is false.
