What is the internal cockpit colour of?

Japanese aircraft in WWII?

IIRC some were a clearish blue, others a green.
Others will know more, but if you have a look at the Tamiya paints range, I think they have some specifically labelled as 'X-manufacturer Cockpit Colour'.

Have a look here:

IJN aircraft used the metallic blue Aotke for their wheel wells etc. When it came to cockpits and JAAC wheel wells it depended on whether they were Nakajima or Mitsubishi. I use White Ensign/Sovereign.

This is a good guide, it also gives a link to much more detailed info.  https://www.sovereignhobbies.co.uk/collections/aircraft-of-the-imperial-japanese-navy-imperial-japanese-army

Aotake is a clear blue to blue-green lacquer used as metal sealer/primer and was applied to pretty much all of the aluminum. It's not a "metallic blue" paint. If you've seen photos of "green" airliners on the production line, a combination of tinted clear coatings and films, it's pretty much the same thing.
My brother has some skin relics from Mitsubishi A6M3s and you can there is surviving aotake under the exterior topcoat and red primer, which demonstrates that it wasn't an "interior colour" per se.

The crew positions, not full interior, of "most" aircraft were painted in a grey-green, this was applied over the aotake lacquer. The Nakajima Green vs. Mitsubishi Green vs. Kawanishi Green is basically a modeller's invention and Kawasaki aircraft had a sandy brown interior colour.

Note that on Army aircraft you can have early types with just the aotake, no green or sandy brown paint, and later types that are just bare metal no aotake or paint at all because of rushed production.

As always bear in mind that the Imperial Japanese Army Air Force and the Imperial Japanese Naval Air Service had almost completely different standards for everything, a grey-green cockpit colour being one of the few commonalities.

The wheel well colour difference on Zeros, and only Zeros, manufactured by Misubishi versus Nakajima is simply one of manufacturing method. Mitsubishi masked off the wheel wells, Nakajima didn't bother and just sprayed them in the underside colour. This cannot be applied as a standard across all types.

Realistically British Interior Green is usable or just buy a paint intended for the purpose. Tamiya XF-71 is one of the options.

I found this website:- https://j-aircraft.com/research/gregspringer/wem-review/wem-review.htm

It seems to have some good information in it.
