Baldeagl, your tone and antagonism are unwarranted. In fact the RAF built many missions in 1941/1942 called "circuses" (and other colorful names) where the main intent was to destroy the Luftwaffe fighter force. The Luftwaffe could decide at whim when to take off and meet the RAF in combat, and when not to. That is, if the RAF was simply running a fighter sweep. If the RAF actually attacked with bombers, the Luftwaffe would take off to stop their fields from being bombed.
The RAF would send a token bomber force, maybe 1 or 2 bombers, but then include 3 squadrons of escorts.
The entire effort was simply to get the Luftwaffe into the air to fight. The Luftwaffe was very much on the defensive (in the respect to their localized environment, not to the overall war) and bright yellow noses gave away aircraft hidden under camo nets around airfields.
I'm not talking 1944/1945. I'm referring to immediately post-BOB, when the RAF was rebounding and taking over the skies. The Luftwaffe was forced to change a number of preconceptions they had about how they could and should fly/fight in the war.
They still put up a very hard fight, and JG2 killed many a SpitV pilot, but that's beside the point regarding the colorful markings.
