MIG-21MF in Vietnam colors

About a year ago I did a replica of a Phantom in Vietnam, now I just started a project concerning one of opponents, the MIG-21MF.
The profiles I'm referring to are the following:

Both are in NMF even if the first has some camou added, but my doubts concern colors of cockpit and landing gear well.
For the cockpit, all pictures I've found shows turquoise green, but for wells I found the same green or something that looks like yellow zinc cromate or grey.
Does anybody have a suggestion for me?
Many thanks
Alberto

The cockpit interior - Russian Interior Blue/Green also known as the Turquoise/Emerald
The wheel bays - it was a grey colour mostly. But also these could be pinted with the yellow-green paint ( eg. Humbrol 226 ) Because of the climate in the Vietnam paints like the green could get various tones including the one similar to the YZC or GZC.

Many thanks for your answer. I think I will do some experiments using colours already on hands, like RLM02 mixed with some YZC and/or GZC, will see!

My mates who serviced in the maintenance crews said it was colour called "brownish green"
