Bill:
We had a similar situation...500' spool #6 & #8 THHN Cu, full spool, factory wrapped).
Was supposed to be "black" and about 40% thru the spool it changed gradually from black to red.
Advised the supply casa, they advised the distrubitor & mfg. Had a call wanting to see it from sales rep. Told him to come to jobsite; he can see both ends.
