Two planes may look similar on b/w photos, but their painting was quite different:
First I-16 was photographed on Pruzhani airfield in summer 1941. It probably belonged to 33 iap
This I-16 was most likely an aerobatic plane painted in non-standard "airshow" colours. It may have been a "personal plane" of a higher ranking officer.
Commander of 33 iap Akulin was a former member of the "Red Stars" aerobatic team... according to memoirs, he flew in a red I-16 during the initial German attack in June 1941. Photos seem to confirm that some I-16s on Pruzhani airfield were red:
one of those 2 I-16s could be red.
There were also several silver I-16s, like No 3
The second I-16 from your post is definitively in white winter camouflage. Photo was probably taken sometime during the winter 1942/43
Below is I-16 from the same unit commanded by HSU Shishkin
