From the Russian press (translation courtesy of Cookie Sewell): 

As of today (4 April 2013) Defense Minister Shoygu has ordered all vehicles to no longer be painted in camouflage, but based on area of deployment to be either dark green, light green, or khaki. 

They were all painted in three-color camouflage a la MERDC using a combination of three out of ten colors: light green, dark green, mid green, khaki, mid yellow, mid brown, light yellow, grey, light grey, and black. Camouflage matters are handled by the 19 TsNII-IV (19th Central Scientific Research Institute of the Engineer Forces) 

According to the maintenance officer of one brigade, vehicles are painted twice a year with up to 40 kilograms of paint per session, timed to coincide with the start of troop training cycles (spring and fall). But takes a month to get all vehicles painted. A single color is easier and faster to apply and if combat is forecast the vehicle can easily be repainted in camouflage. One color only takes 1-1.5 hours to apply per vehicle.
