Lew, I find that the Black & White monitors have much better clairity and sharpness (Both daytime & nighttime) than the color systems. This may not be the case with the newer set-ups as it has been about a year since I have driven in a coach with a good high-end color system. I also understand that certain systems have COLOR cameras, but B&W monitors, so if you want color all you have to do is change the monitor. I have never personally talked to anyone that has had one though. I am sure someone that has changed theirs out from B&W to color will join in the thread soon and let us all know how they like the change to color.
Good luck - Glenn.
