The first meteors that were based on the continent were painted white to avoid confusion with the very similarly looking Me262.

Does anyone know how good this painting job was done?

were these things really white or could you still see spots of the normal grey-green camouflage?

any info or reference pictures highly appreciated

Only a few Meteors were painted in this manner. The reason is not known. It is said to have been to avoid confusion with the Me 262 but another possibility is that it was for ground camouflage during heavy snowfalls in Jan, Feb, March. From photogrpahs it appears only one coat of white paint was applied which may have been a semi-permanent distemper. The white finish was sprayed around the national markings and serial numbers, the later being left with the original camouflage background. In some cases the serial letters were overpainted and only the number part remained visible. e.g., EE239. Squadron codes were removed from the fuselage but the aircraft letter was painted on the nose undercarriage door.
