The Kookaburra 70 is a bit toneless on the original card too, but compared to the schwarzgrau 66 to its left, definitely has some green in there somewhere. For sim skins, some 'scale effect' is clearly needed, and all those colours, however accurate they may be, would need toned down when not applied to a full-size aircraft, and then weathered on top. Sim skins are more like scale models in that respect, and for the latter I was happy to use the Hannant's Extracolor range, which I see is still in full production:
https://www.hannants.co.uk/manufacturer ... r/products Apart from interior colours they come in gloss finish for better application of waterslide decals, being designed for a coat of matt or satin varnish on top. With that coat toning them down a tad, I liked their colours for 1/72 models. I still have several of their tinlets in my modelling toolbox, not opened for over 15 years.
The restored White 14 looks too shiny and factory fresh and the CloD 109s, while not so shiny, look a bit too like that for my taste. I know the Luftwaffe supposedly used a semi-gloss finish but some pics trotted out to show that are a bit dodgy (like that Jagdgruppe 50 pilot leaning on the tailplane of his white-tailed Gustav, which, that unit being intended to catch Mosquitos, was quite likely polished, as Heinz Knoke records was done to his one of his 100Gs). Apart from some certainly somewhat shiny examples, most 'in service' pics as you will have seen show 109s and other German types looking about as matt and scruffy as their RAF counterparts, whose finish Michael JF Bowyer describes as 'very rough when touched, thick and very matt so that the aeroplanes gave the impression of being very badly finished' ('RAF Camouflage of WW2', Airfix/PSL 1975).
The Heinkels in BoB2+BDG2.13 do look a bit light in tone, to me; otherwise, I think the stock multi-skins are up to the very best standards of the best-finished plastic kits, and a tribute to those who produced them, a hard act to follow.
