Help needed from aficionados, please!

About to pull the front end off my car for repainting and have a query on the colours. It’s a standard dash, pretty base level car, not an R/T etc, so pretty comfortable that dark argent (which I have paint for) is correct for the main grill panels and the filler panel.
Am I right in saying that the egg crate part was just polished ali? Don’t think that is argent too, or can anyone confirm either way?
Last one is the headlamp bezels. I’m getting conflicting info on colour there, some people say they were black on all models, others say they matched the argent variants where necessary.

Any help gratefully appreciated!
