Hey 66:
What "romex" you talking about???????

BTW, we have used "striped" neutrals....
Had a electronics mfg plant that had some stringent and strange specs....
White w/red, pink, yellow, black, orange...
Green w/ (matching the above)

The above was installed to feed electronics racks from a "clean" sub-panel...
Besides the strange colors, everything was numbered....
Wsa a real good client until they went "belly-up"
