I take it you added the color hue's on the hull to the texture itself. You could probably get a more accurate look by making the hull solid white, and adding the hue's to the specular maps.(an idea which I have been meaning to try myself at some point.) Since the colors only really came out from light reflecting on the hull at certain angles, which caused the pearlecent sheen seen in TMP.
However, I should add that your aztecking is nearly perfect. Not so sure on the secondary colors, but then again there's no definite reference pics. Though most of them look like they should.
