Champagne Gold and Ermine however I did change the roof colour slightly to a more creamy white rather than the stark white of the Ermine not that you can see in these pics.
You have a very skilled body and paint guy doing the work. Very nice work it appears to me. I love the 58 Imperials, and they were easily the best looking models of the 57-59 years, especially the grille treatment. That is my favorite color on those models too. Looking forward to seeing it finished. You should be very pleased at this point.
