Which "viking blue" looks most like the

From the computer pics, i'm going with #4 and #8.

like stated earlier, it's hard to determine from a computer.

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.

And I don't think image #7 (the #19 car) is Viking Blue at all. That looks Guardsman Blue to me.
