Chengdu F-7M wheel bays color?

[IrishGreek]

Subject says it all.  What color should I paint them and the gear for a Chinese example?

 

I found a 1/48 kit by a maker called AA that I am starting.  Pretty simple kit, but trying to get it correctish.

 

Also, I am thinking the cockpit looks to be that light bluish color. 

 

Any corrections appreciated.

 

Thanks. 🙂🙂
