I can remember the days when the hobby shops just had the one rack of little square Testors bottles-40 or 50 of them, 49¢ each in various colors. There were a couple of specialty colors like insignia orange and zinc chromate, and even Olive Drab. That last one not being labeld as to whether it was meant to be Army Air Corps OD, WWII armor OD, unitform & webbing OD, or even post war hues of those.
Scale Modeler and, later, Military Modeler gave us our fist glimpses at people who cared enough to note the differences. The veyr beginnings of the Osprey books were starting to appear in hobby shops, too, so we’d have a reference.
A well-rounded hobby shop would have a rack of Floquil paints, a very-fine ground pigment paint in a xylene carrier which evaporated very quickly and was aimed, very sepecifically, at the model railroad crowd.
An extremely diverse shop might also have the 16 or 24 colors of Practra flying kit "dope’ paint, which was way too “hot” for styrene, but had its usese.
What a miracle it was when those glorious tins of Humbrol paint showed up, that let us paint armor kits practically “by the numbers.”
We did not have the resources to know RN had a “Western Approached” paint scheme or what colours it was in; we barely knew that the USN had used camoflage in a war that haf completed only a scant thrity years previously. Battleships were grey, all over, decks, hulls, everything but gun barrels and those were black.
Scale effect would not become something we considered for most of another twenty years. Scale effect occurs in ship subjects becaue, for a 1/350 kit, as 12" away you are viewing the kit at a scale 350 foot distance. It will have an appearance of being much paler, lighter in hue, than if a person were standing upon the ship’s decks.
