I was searching especially for an early version of RLM 02 Grey, and found it on the website below.
Now the modellers among you know, we can be pretty "anal-fixated" about detail and research.
But nevertheless, I really found two versions of that Grey.
It had a different tone until 1940, when it was slightly changed.
At "The Aerodrome" I have asked Dan-San for his opinion of the factory colours of Albatros hoods,
and he replied, that until the D Va, all hoods/cowlings were factory-painted in the grey, that was
later called RLM 02 - as I had assumed.
Now, here are the two versions of the RLM 02 - as I said - you may not find much difference.
Later, the hoods were of course field-painted to the likes of the Jastas, or even single pilots.
Lots of colour samples here:
