This is perhaps the one I was most excited at having another go at. Originally, the markings had been drawn very accurately, but the colors were well off the mark. This time around I wanted to try and make it the closest depiction to the original than has possibly ever been done (including in scale model form).
In original photos of "Lou IV" the camo paint that was applied to cover the tops of the invasion stripes is a lighter shade than the other camo paint that had already been applied previously. Using color chips of '44 era USAAF Olive Drab and British/RAF Dark Green (as far as I know, the only two camo colors that USAAF ETO-based units used for field-applied topside camo) I was able to check them in grayscale/B&W and confirm that the RAF DG is quite a bit lighter in shade than the USAAF OD. It also makes sense based on information that I've heard/read that suggests the 8th AF Fighter Groups initially had access to USAAF OD, but once that stock dried-up they used British paint. I think this is the only color combination that makes any historical sense, and again it meshes well with the photographic evidence. Some have tried to argue for insignia blue having been used (due to poorly developed color photos that have a horrific blue cast over the entirety of the photos), at least in the section where the invasion stripes were painted over, but one can see in the original B&W photos that the values are quite different between the insignia blue of the stars & bars and the paint over the invasion stripes. Also, there was no precedent for ETO fighter pilots wanting blue top surfaces on their aircraft for camouflage purposes flying over Europe- it was always camouflage green (whatever green they could get their hands on, either USAAF or RAF). A number of 361st vets over the years confirmed that they never used blue on their aircraft.
I chose to use RAF Trainer/Insignia Yellow for the nose, figuring that was the likely source for that paint (the yellow bars surrounding the "Lou IV" name are a bit darker, as can be seen in original photos - that bit of nose art had already been in-place prior to the yellow nose markings being extended back to the firewall). I also re-drew the "Athelene" name/sign artwork on the starboard side to be more accurate in positions of the letters and design/shape of the sign. Although others have argued/debated it for years, I am 100% confident that the area around the gun ports on the original was just the silver paint of the wing, exposed where that section of the wing was masked prior to the application of any paint. In one of the several original photos, the bottom surfaces of the aircraft are clearly shown, and one can clearly see that the leading 50% or so of the silver paint of the wing was very dark on "Lou IV", hinting at the dark "Acme Grey Surfacer No.53N5" that was applied to the wing in that same region, below the paint, was effecting the hue/shade of the paint, and this would point to why the region of exposed silver paint around the gun barrels wasn't particularly bright - at least not as much as the silver rudder or back half of the painted wing.
