Not hangers as such but the Steel works in Corby had most of the main buildings in an alternate green and brown banding. Fairly wide strips too. They're sizeable buildings! Of course, the majority of it has faded now unfortunately.
I'm not sure what the correct scheme would have been for RAF installations though. Once the Luftwaffe had turned their attention away from the airfields I'm not sure if more than just a general green colour would have been needed.
