I'll throw my $0.02 CAD in...
I believe Guardsman Blue has a metallic/satin finish to it which will reflect the light and make it appear lighter and darker depending on the angle you are looking at from. I think metallic paint is difficult to capture in a photograph because of the properties of the paint and if the lighting, exposure time etc are incorrect.
Your local automotive paint pro would be able to give you the right answer - may not be as easy to just add Black.
