Question about color scheme of North Korean Mig-23ML Floggers

I have some references that depict a color scheme of overall silver for the Mig-23ML in North Korean service. I believe these photos are misleading as all other references show a slightly gloss overall air superiority gray. Can anyone shed some light on the correct color of North Korean Mig-23 ML Floggers?

Here are some photos:
