The original lead is black. When I have used NOS conduit and lead as this is how it comes from the maker, I have sweated off the terminals and replace the lead with a modern equivalent 2 inches longer and re-soldered the terminals back on. This is because the 70 year old lead is stiff as a board and hard to bend up to the terminals on the solenoid, and the extra 2 inches makes this also more achievable. You can also use black heat shrink on the ends.
