A history of Zinc Chromate:

Generally speaking...yes, there is two...with all sorts of variations of those two!

Testors makes a nice chromate yellow. I've only found it in the small square bottles(enamel). I have yet to find an "interior green" that looks good. I mix my own, with Olive Drab and chromate yellow....looks way better than the cartoon green they try to pass off as interior green.

As far as which is correct...well...both! Although, I can't recall seeing a cockpit done in the yellow...which is common for other interior areas...gear bays, gun bays, etc. You can have both on the same aircraft as well. 

There's also another green...."bronze green" that was common in the B-17 and P-47, to name a couple. It is darker...Model Master "Medium Green" is pretty close for that.

Basically, check your refs to get the right color!

Aaah which zink Chromate....that is the question. 

Well Mr Ardvark, the simple answer is they used both. It depended on what the manufacturer sent and what they had on hand. To confuse matters even more the color shade would vary from batch to batch.

You won't really go wrong with either but green was more prevalent. 

There is a link floating around here somewhere that goes into great and boring depths of Chromate.

I'm sure someone will dig it up.
