Ah Pactra... they had some great flat colors. They had a Dark Olive Drab that was an excellent match for the color in use at the time on US Army vehicles... their Pactra International line of military colors sold at hobby shops had an Olive Green and Khaki shade that were perfect for US uniforms, and the Flesh color, flat and with a hint of a suntan look, in that line was not the comical apricot or pasty cream glossy colors that I had previously had to use.
Just like the Floquil & Polly S/Scale paint lines, Testors bought up their competitors, then later discontinued them. Boooooo Testors...
