if you say canadian voodoo gray is similar, you ca use it as the basic color.
It's all about color mixing.
I did mine superiority blue, it took some while to do, but finally with the modellers instinct (and lots of good pictures) you get the job done.
I always mix colors, and cannot rely on all FS numbers.
Some of them (the F16) were also incorrect. The darker grey is like an sharky one.
Looking at pictures, most eagles (desert storm) got sunburned. They got more purple, but that is once the picture have been taken with no sunblocks!
Just find your neutral photo, and go from here.
