Depending on the period that LC wants to depict his model, the brown may or may not be faded. If it was shortly after capture, the paint would be reasonably fresh. Note that the colour pic above does not have the yellow outer band in the fuselage roundel and the bottom does not appear to be yellow.
I agree. It seems that the bomber was repainted a couple of times, especially at the national markings. Here is my attempt to get the chronology ...
As memo serves that is a shot taken soon after she was repaired and made airworthy. The second one seems to be taken at the same time. The RAF serial was of black. No traces of overpainting of the national markings yet. But the work on the camo painting seems to be finished contrary to her appearance in the fist image.
IMHO, this image of her should be here. I mean, between the initial state and getting ready to the participation in the move. Please note the black serial was overpainted. There aren't any additional traces of overpainting markings. Also she got the new exhaust pipes.
Here a pic from the movie she starred in 1941 or 1942. For the reason the LW markings were restored and the RAF signs overpainted. However the exhaust pipes aren'r seen clearly. But I would say these were of the later type.
Here a couple of images of here with the RAF markings restored. The LW markings + the swastikas were overpainted again. Please make a focus on the traces of overpainting on the fin and fuselage. The white serial was applied.
Here still with old style markings but the camo was getting worse. However some areas of her seem to be re-painted. ..eg, the top of the fin. The yellow ring of the fuselage roundel can't be seen because of the plane moving and poor copy of the freeze-frame taken from a movie, I would say.
And here the RAF markings of the new style were applied.. but the camo looks very worn..
Here, I'm not sure but she might have been repainted again but looks quite dusty.
