What is the oem color for engine pullies

Hi, I am restoring my Z's engine, so I am in process of doing the items like the camshaft, alternator and air pump . My question is; what is the stock oem color (number) for these types of pullies? I thought I saw post before, but can't find them now. I Thought they said use to duplicolor DE 1621 Old Ford Blue as it was a close match for some of them.
