Hello All,  In looking at a photo of refrigerator car, IC 50302, on Railroad Picture Archives, http://www.rrpicturearchives.net/rsPicture.aspx?id=671230

I am wondering what was the paint color of the ends and roofs.  In this photo it appears it could have been black or orange?   Which color was it?   Thank you for your time and effort to help.   Lester Breuer
