Yes, for as jaw-droppingly stunning as that DCS P-47 skin is, I don't think the tail color is correct - especially after playing around with the latest color photo Lyric found.
No matter how much I try to tease the yellow out and lighten/brighten the overall image, the tail color doesn't appear to be as light/bright as ANA 501. I would guess the DCS skinner read the documented "medium blue" or "light blue" for the tail, looked at existing profiles, and then chose a color that best represents medium or light blue to his eyes.
I'm unable however, to get that color photo to corroborate his color choice, or even ANA 501, however I tweak it. The real color of the tail appears to be quite a bit darker than ANA 501, but not as dark as Insignia Blue. So I think you might be onto something with the idea of a field-mixed custom color blue for the tail.
There is the question of how much Green is present in the color. None of the written documentation we have suggests there was enough green to be evident to the documenter - the color is merely listed as Light Blue or Medium Blue (which does leave open a pretty wide range of values).
One of the complaints about early color film is that it yellows as it ages, besides experiencing color fade and darkening. And each of the component colors in the film can degrade at different rates, muddying the water further. I think its possible that 'yellowing' of the film as it aged has introduced a bias in the blue tail color toward green, resulting in the dark blue-green or teal shade we see in the photo today. But its beyond my crude Photoshop color adjustment skills to really test that theory. No doubt someone with intricate knowledge of the aging characteristics of the film used and much more skill at restoring photos could achieve better results than I did.
