another source says the Earth Brown FS 30219, Olive Green FS 34127 or 34096, Blue Grey FS 35526.The cockpit interior Grey FS 36622 and Dark Grey FS 36231 for the rest of the plane interior. The yellow colour like mentioned above.
The statment made me curious about that..... General info says that the planes of numbers 1-300 were painted with the camo that wrapped around the entire fuselage at the rear area. The kind of the camo was used in 1940-1942. However, I decided to have a close up look at the existed images of the Romanian I.A.R. 80/81s. Here is what I found. Generally, the undersides were painted with the blue-grey colour for most of the planes. Usually, the demarcation line between the top colours and the bottom one was at the bottom main stringer of the fuselage. See pics below.

However it seems there were planes that had the demarcation line moved a little bit down ... that might be the reason for not noticing of the bottom colour especially if the pic was taken on a sunny day. The shadow at the bottom of the fusealge makes the trick and doesn't allow to see the undersides fully. Also the quality of many pictures does the same. However using the Gamma correction it can help. Please look at the enlarged shots below... the thin lighter line at the bottom of the fuselage ...

Because I couldn't find a shot of the "White 42" of a very good quality and size I have taken a screenshot from the documantal film. Initially the bottom colour can't be noticed but when using the Gamma correction a kind of a thin lighter line at the fuselage bottom may be seen. IMHO it might mean that the plane could have had the demarcation line of colours moved down. At least at the time the movie was made. But certainly I might be wrong. Anyway, no a straight answer.
