Look at the OP's orginal post #1 . He has done the headlight trim ring in black as well. It does not look bad and he can do as he wish's, but I agree with rklein383 that silver on the ring stands out better and for the purist is correct color.
I read the OPs post. To me(by his pics) it looks like the headlight ring is painted black on the outside, and on the inside(facing headlight) looks argent/silver.
I have never seen the plastic headlight trim ring painted black.
When I said I vote "black" that was for the core support, NOT the headlight trim ring.
