Tony, not sure if the Matador would be around in the BoB period, apart from on bomber bases. The colours would be Dark Earth, with a very dark Green 'Mickey Mouse Ears' camouflage pattern. Later, these were also seen in overall dark earth, often with a faded cammo pattern. The RAF Blue, with the yellow top sides, was introduce post war. Immediate pre-war, the vehicles were overall RAF Blue, changed to either overall dark green, or a described above, on outbreak of war. There were a few exceptins for RAF vehicles not always on airfields, such as Staff Cars, Utility trucks etc, which could still be seen in RAF Blue, but mainly it was as described above, for all vehicles.
