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.
