Color is cool, but for decades now, the push has been to increase low light level sensitivity and for good reason. Lack of sensitivity has been the principle handicap to NVG.

Information about any loss in sensitivity due to going to a color system is precisely what Jones left out of this article. Color vs. threshold sensitivity is a natural consequence of the physics of the sensors involved and that tradeoff can sometimes be quite serious. For example, in the human eye the rods (black & white sensors) are 400 times more sensitive than the cones (color sensors).

I'd be damn sure that I truly needed the color system before I would switch to it. Someone's life may depend on it.

I'd hope it would work both ways. Present a picture in monochrome in extreme dark situations, and turn on the color when the light is sufficient.
