Generally speaking though, helicopters by Mil that have been delivered since this summer are gray and this gray drab has signature reducing qualities (radar/IR). Prior deliveries retain their usual camos for the most part. Many machines also got a freshened-up paintjob together with the introduction of the new Air Force roundel.
The Kamov Ka-52 was black at the pre-production/evaluation stage, later it recieved the usual green/tan combat helicopter camo. The gray machine that was seen at MAKS was a Ka-52K for the Navy, if I recall correctly.
This lack of a wide "standard" is also evident elsewhere. MiG-29SMTs were fairly recently given a gray/white splinter camo (reminsicent of the Sukhoi Su-35BM bort 902 and the PAK-FA) whereas other MiG-29 models still possess the USSR-era green/gray camo. A notable exception being some MiG-29UBs that have recieved an all-gray variety. In the Sukhoi case you see some versions of the classic light blue scheme in service, both for Su-27/30 and the recently adopted Su-35S. Prototypes, tech demos and what not have sported a multitude of schemes. The Su-34 has its own version in a deeper shade of blue for a while (the early machines had a greener kind though), but a few of the aircraft in the latest batch delivered to Baltimor AFB in Voronezh have recieved a new all gray camo.
I think the overall trend is simply to go gray. Evidently, it's on the increase and I find it quite likely that they will standardize it to a larger extent in the near future. Bit of a westernization, I'd say.
