Bish and Gamera - thank you.
In April of 1944, Britain issued S.C.C. 15 as a colour equivalent of US Olive Drab. A very close match, only after fading was a difference readily detected, as it would become more green. It is unknown whether Fireflies were completely repainted in this new paint, as orders specified there was to be no wasteage if the lone purpose was to make all vehicle colours uniform. There certainly would be a fair amount on the turret due to modifications with the new 17-pdr. Perhaps the hull, depending on how much work was required for the seabourne invasion.
I used one of Mike Starmer's suggested colour mixes for Tamiya paints:
5 parts XF81
1 part XF58
1 part XF71
For the first spray coat, I tried something different by adding close to 50% red to the mixture, reason being two fold. First, this would help in conveying an olive hue. Second was sort of a test on the colour wheel theory dealing with complimentary colours. The compliment of green is red, and mixing the two resulted in what looks close to a hull red. This deeper shade would be useful in shadow areas while at the same time still remain vibrant.
Second, to introduce the S.C.C.15 mix onto the model, I decided to add a few drops of red into the airbrush cup. With the smaller scale build, it was difficult to retain some semblance of the first layer without compromising coverage in non-shadow areas. (pic #2)
Finally, the original mix was applied, concentrating more on the turret. You have to look closely, but you can see a bit more of a green tone in pic#3.
