A topic of discussion for visitors at the Cold War Air Museum has been; "What color is that?" Or; "Why did the Soviets paint their cockpits green?"
We don't worry too much about making an exact color match to some mythical factory standard, but we do make a color match for individual aircraft when necessary during restoration. Besides, we are mostly guys, and most of us simply made it through kindergarten with the 8-count box of crayolas, not the 64 count box (I don't even know how they come up with the names for so many colors). While the paint store most closely matched the blue-green above with a commercial color named "Mermaid Green", it's just not right to say "Our fighter cockpits are decorated in Mermaid Green". So for now, we'll just stick with something that fits within our limited repertoire and continue to refer to all of these colors as simply blue-green, or more simply as just that "Russian Cockpit Color".
