i think there's some history here too, just gotta dig up the old timers..... [Linked Image]

from my '68 nec...
210-5 Color Code;
(fourth sentence)

All circuit conductors of the same color shall be connected to the same ungrounded feeder conductor throughout the installation.

this also reads in the '71, but the colors dictated in the '68 were arranged into a FPN ( or what appears to be a fpn?)
