Lloyd - Well, I tried a bunch of different angles, including the Dykem dyes (too dark, didn't stain well). I called various platters, no luck. I tried reproductions (color way off and the clips aren't even close). Finally, I went into a Hobby/Craft store and they had Testors 1257 Translucent Blue. Intended to paint model airplane cockpit glass...so I said, what the heck and gave it a try. I just dusted the clips with the spray paint and found it to be visually pretty close. So that's what I ended up doing. Not factory correct, but optically, I'm reasonably pleased - though ideally I would have preferred a true translucent metal dye. Let us know if you find a better option!
Here's a comparison:
All the clips, based my observations of the color after cleaning - some clear zinc, some yellow zinc, some black zinc, and finally translucent blue
