While digging around on the internet for info/plans for the Fairchild PT-23, I happened across this bit of info concerning color schemes on US Army Primary Trainers. This is from the GoldenWingsMuseum site...and used without their permission...please don't flog me!
Paint scheme differences also appeared as production progressed. Prior to June of 1942, all U.S. Army PT's were painted with the then-standard blue fuselage and chrome yellow wings and tail. The aircraft rudders featured a single vertical blue stripe and horizontal red and white stripes. From June 1942 on, all production Air Corps trainers left the factory with an all-silver finish. A common restora*tion error with PT's is the application of the blue and yellow paint schemes on aircraft manufactured after May 30, 1942. It fact, only one PT-23 was ever painted blue and yellow and that was the factory prototype. Another significant change was made in August of 1942. Then, the red center spot in the white star, a tradition since 1927, was removed as of August 18, 1942 due to the similarity with the Japanese national insignia; The red, white and blue rudder bars were also dropped at the same time.
For those interested parties, Chrome Yellow has a RGB code of 252, 222, 40.
