Original cobras were painted in often whatever was available. White, blue, red was all fair game. I believe Viking Blue was the original blue or a Shelby racing colour and that I believe morphed to Guardsman which is a deeper blue. There are many on CC that have a lot of this knowledge. I suggest you do some searches here on the forum as the history about colours and engines have been discussed many times.

Edit - educated myself and the comp and S/C came over from the UK unpainted. There is a list of original colours for those and Guardsman was one. The mk I and II had a list of colours and Princess Blue (UK) became Viking Blue.
