The profile of the Tu-2S „Blue 20“:

The photo shows Tu-2S "Blue 20" built in the Factory 23 on October 1944. The plane seems to be painted in the standard three-tone camouflage scheme except upperwings which seems to be painted overall light brown as seen on many other Tu-2 planes.

It is not clear whether the tail upper surfaces are also painted light brown or it is only the light reflection. Rudders alone wear the standard camouflage.
