If you want a color code in the NEC, it's simple.
Submit a proposal. It's too late for the 2017, but you'll have plenty of time to prepare for the 2020 to collect your substantiation.
Speaking of substantiation, what would you proffer?
Proposal...all conductors shall be black.
Substantiation...if all of the conductors are one color you would have to have some electrical knowledge to work on electrical systems.
