You can take 10 different pictures of the same car and get 10 different colors
depending on the lighting, angle, etc as has been already stated. I never realized
just how true it was until I had my coupe painted. Inside out of the light,
it looks silver. Out in the bright sunlight, it looks blue. Overcast sky and it
really looks like a different blue.
While I wanted Viking Blue, the MAACO shop I was dealing with said Sherwin
Williams didn't have the color available in a 2 stage paint, only a single stage.
Since I wanted base/clear, Sherwin Williams said the closest match available
in a 2 stage was 1985 Porsche Lite Iris Metallic which is what my coupe is painted.
