SUPERFLY,
Color schemes for VVS aircraft were two-tone grey camoflauge by '45. The picture below (Azrael's post has it too) is of a Yak-9U at Monino. Aper has some good pictures, those last two (White '10' & '22') looking the best.
Also, in Morgan's Osprey book
Soviet Aces of world War 2 you would be within VVS regulations if you gave the Yak-9U the color schemes from plates 29, 34, 35, or 36.
Finally, SUPERFLY, check this
site out as it is quite comprehensive on VVS color schemes during the GPW.
