ECN Forum Forums General Topics of the Trade General Discussion Area Feeders -- Colored or black with ID markings?

A silly little question which popped into my head. Thinking back on the dozens of photos posted here, it seems to me that the majority of singles pulled in for feeds and sub-feeds are black with appropriate ID colors applied at the terminations, taking advantage of the NEC rule about conductors larger than #6.

So when pulling feeders such as #2 and larger, how many of you keep stocks of all appropriate phase & neutral colors and how many just stock black and mark the terminations?
