Do the iraqis really paint their aircraft themselv

I´ve seen alot of colour profiles in magazines foremost iraqi Mig-21s in a uniqe for Iraq two-tone sand and brown scheme.
But i´ve come to wonder if the iraqis really do some painting themselves because REAL photos of all iraqi aircraft i´ve seen (MiG-21,23,35,29, Mirage F1, Su-25) seems to have their factory scheme (or schemes from overseas overhaul sites-Yugoslavia, East-Germany, Lithuania etc.)

Is the nice sand and brown scheme for real or is it a misinterpretation from black and white pics?
And in that case what scheme would a iraqi Chengdu F-7B have?
Chinese 1980s delivery scheme or like the F-7s from Egypt????

Grateful for answers
