British camo colors 1941

According to (British) Army Camouflage Directives of the summer of 1941, soft-skin vehicles were to be painted Khaki-Green #3, with wavy bands of Dark Tarmac #4 (a VERY dark black/green). Would this also apply to RAF and air-base associated vehicles? Or (since this is Army Directives) did RAF retain their blue/gray colors during this period?
