Not sure buddy, but I have found that Modelmaster Panzer Olivegrun 1943 is different to Testors Panzer Olive Green.They are shades different. Modelmaster/Floquil/Polyscale are all Testors manufactured but there are color differences despite names being the same if that makes sense.
Thanks Boba..It sure gets confusing with all these colors! Trying to find an exact color can be difficult.
Another good example are the 2 tops of the ESB Jetpack canisters..I see a lot of mustard color,,but looking at the movie screen shots..it looks more dull brass than yellow..
