The multi-colors thing in EFIS is overkill, also. Every EFIS uses different colors for different information, they don't use varying hues of the same color for different information. As long as someone can distinguish between magenta and red, etc; who cares if the way they see magenta is the same way that you see magenta? That's why they have functional evaluations for those that do require waivers. The engineers and human factors folks design the displays to be usable with the current standards.
Civilian aircraft have been using multi-color EFIS for as long or longer than USAF aircraft, but the FAA has seen no reason to change their color vision requirements and there has been no spike in color vision related mishaps.
