The USAAF issued different color instrument rating cards for different levels of competency, the old joke was that if the color of the sky matched the color of your card you could fly in the given conditions.
Tom-
All joking aside, I don't know what color USAAF Instrument rating cards were in 1944 but ten years later in 1954, they were either green or white. There were extra qualifications required and priveleges granted for the green card holder. The white card was the basic USAF instrument rating and until about 1956-57 only the green card rating could be used for issuing the CAA (civilian) instrument rating on a CAA pilots license without the CAA written and flight check. The "blue card" was only valid in jokes!
Fortunately for me, when I was getting ready to get out of the USAF and hopefully fly as an airline pilot, I had passed the written exam and was getting ready to learn how to fly a Piper Tri-pacer for the check ride when the CAA said that the USAF white card was now a real instrument rating.
I had tried to get clearance for a CAA Examiner to go along on my last USAF Instrument Check Ride in a KC-97 but SAC said no to that idea! The CAA said was OK to fly a military 4 engine transport in weather but if it was a civilian 4-engine transport, I had to pass an instrument check in a Tri-Pacer first! Go figure.
