Sovietwarplanes

I guess July 1941 is confirmed

Have you considered A-18f light blue for the lightest colour?  Why gray AE-9?  On SB bombers AE-9 disappeared in summer 1940...  IMHO this is a field applied black-green scheme further modified with light blue on upper surfaces (isn't that exotic!)

I'd never seen Peshkas painted in that kind of camouflage before.  It would look good on a Shturmovik, if only I could find some photographs.

Personally, I like to keep things simple and logical.  Two green colours don?t make sense to me.  We have already been there: dark green-green scheme didn?t exist and those planes previously interpreted as dark green-green were actually green-black.  Same here, what you see as darker green is most likely black.

Examining all the photos, I am convinced that there are at least four colors on the uppersurfaces.

I am just making an observation.

These Pe-2s have similar tonal contrasts and patterns to the experimental 1940 schemes, given that The I-16 is on a cloudy day, the Pe-2 in direct light.   

you are joking, of course. Zinc chromate yellow ins't a camo color nor in air, nor on the ground. I don't see doubts that the colors were overpainted to the green.

On the Finnish wreck, the border between grey-blue and yellow is chipped, not as we see on the wartime photo.

It is fascinating that several photos of different planes exist, but all are wrecks in German hands, from the summer, judging by the bright light and vegetation.  Is there any more information on the photos sources?  (eg from one German unit?)

Perhaps test unit with documents lost in the chaos of 1941?   

I don't understand your belief that the shade of yellow visible on the photo was utilized as camo color.

I don't understand how you can see dark green, brown, cream and light gray on those b/w photos.
-  Dark green 3B was discontinued in 1938
-  tobacco brown was nitro paint for fabric that never went into production
-  cream was nitro paint for fabric covered civil planes and also never went into production
-  light gray AE-9 was supposed to be overpainted according to June 1941 directive

Do you agree that the rudder structure (dur-alluminium ribs and spar) on following picture was protected with yellow ALG-1?

Do you agree that the front of the tailplate and tailcone were the same colour?

But look at the shade found on the Pe-2:
(http://i292.photobucket.com/albums/mm13/klesnikov/Fence_airfield/Pe-2No35lbls.jpg)
it looks like a canary yellow. And it's likely the color visible on the strut on the bw photo.

I strongly believe that the factory didn't deliver unpainted planes, but painted in green and light blue....

It's not nice to tease, чувак.  :P

If you need the template to trace your drawing with photoshop, I can send it, of course.

However the planes have a big variety of colors from light to dark and are represented in many photos, so it can't be a color as 4bo that is already represented by a-19f.

Seriously, it was a regiment "особого назначения" (Special Purpose)  8)

Important role in bringing the Pe-2 to "performance standard" was played with creation of 410.BAP NO from the NII VVS under command of Colonel A.I. Kabanov, who was before the war as deputy head of the Institute flight part. Under his leadership in July, dive bombing was worked out. Regiment was immediately involved in combat operations in the Battle of Smolensk.
First sortie of the regiment was made ​​in full (32 crews) to bomb the crossings of the Western Dvina. The enemy suffered heavy losses.
But the regiment paid dearly. From 5th to 28th of July 1941, its losses amounted to 33 aircraft. Every third plane was not lost in aerial combat. Three Peshkas crashed, three were destroyed by German bombs on the airfield, two had to be burned during the retreat, and the disaster happened. The rest were shot down by fighters and anti-aircraft guns, making an average of less than 11 sorties. According to flight crews, such large losses were attributed to failure of weapons, as well as weakneses of the armor. Gunner Ratnikov who managed to bail out of the burning aircraft  wrote: "There is nothing more horrifying than when you see the enemy approached closely, look him literrally in the eyee and can not destroy him because of the refusal of weapons."

Enemy quickly identified weaknesses of Peshka and changed tactics of attack. If you have previously attempted to shoot down Soviet bombers on a collision course, then later experienced German pilots and foremost commander Lt. Col. V. JG 51 M?lders began recommending prosecution of Pe-2 from rear, firing short bursts from long distances, and in the event of lack of return fire closing in and shooting at point-blank with incendiary bullets into central fuel tanks.

In response to such German tactics flight and technical personnel of 410th Regiment began the search for adequate measures. In particular, immediately offered to improve the turret, changing the design of flexible ammo supply; mount side firing point with the possibility of moving the machinegun from side to side; mounting a remote machine gun installation in the tail cone (it was developed by designer Mursev). All of these improvements were adopted over time. However, 410th Regiment fought for a short time: in October 1941, it was disbanded and specialists were withdrawn to continue working in the rear.

Same debate thanks KL for hints on this interesting story:
