Hi Tom! Need your help. Apart from the cammoed variants, I have seen Bis Fishbeds for the USSR in grey, but I cannot determine If the planes were left in natural metal or painted in some kind of light grey. My question is, anyone know If the planes were painted in grey or left in natural metal? If painted I will need the name of that grey and If possible the RGB values for it.

in the sixties they were left in natural metal finish, which made sense as they were mostly used for air to air, only a few panels were painted .

Early grey Migs were painted with various acrylic lacquer paints. Most used paint in outer skin was type AK-113F covered with AC-16 lacquer with 7% aluminium powder and finally with clear AC-16. Source Mig-21 in Finnish air force by Jyrki Laukkanen.

Thanks a lot guys!
