Well, it's a tough question to answer. The best I can do is reference you to the IPMS Stockholm site on interior aircraft colors.

Some may argue that this is not comprehensive, but it's not bad information. Here's the relevant part that may interest you.

Vought F4U Corsair
Sorting out the interior colours of the Corsair is particularly tricky. For the F4U-1 Birdcage Corsairs, photos taken at the time show the cockpits being a very dark colour, most probably black. Analysis of some crashed examples of F4U-1s indicates black, while the factory Erection & Maintenance Instructions called for Dull Dark Green.
As mentioned before, early production Corsairs had their interior surfaces in areas other than the cockpit covered with Salmon primer. This colour mixture was used relatively long into Corsair production. It would seem that all F4U-1s and a number of early F4U-1As were finished this way.
Somewhere during the production of F4U-1A model Vought discontinued the use of Salmon primers and switched to Zinc Chromate Yellow with cockpits in Interior Green.
In the engine cowling area, Vought adhered to the practice of painting its inner surface the same colour as the underside, ANA 602 Sky Gray on early F4U-1s, ANA 601 Insignia White on F4U-1As.
The wheel wells of early model Corsairs deserve closer inspection. Like the cowlings, the main wheel wells, undercarriage legs and both sides of well covers were painted in the underside camouflage colour, ANA 602 Non-specular Sky Gray. Wheel hubs were silver. However, the smaller forward area of the wheel to which the leg itself retracted was left in the factory primer finish, Salmon. Some aircraft had also Salmon inner surfaces of the small covers attached to the undercarriage legs.
The canvas covers in the wells were probably drab-coloured.
With the advent of the tri-colour camouflage on F4U-1A the same principle was applied with white replacing the Sky Gray with ANA 601 Non-specular Insignia White, and the However, the undercarriage legs remained grey throughout the production of this model, possibly due to the failure or indifference to notify a subcontractor about changed colour specifications. For the record, some photos of -1As seem to show silver undercarriage legs, but it could not be established to what extent such finish was applied. One theory is that Aluminium lacquer was applied on these assemblies during field depot overhauls.
In October 1944 the new factory instructions for the F4U production called for application of Interior Green on all internal surfaces including the cockpit. As an anti-glare measure, all cockpit panels above the lower edge of the instrument panel were to be painted matt black. Curiously, the new directive did not explicitly state what was to happen with the cowling's inner surface. Thus, subsequent machines showed either Zinc Chromate or Interior Green cowlings, until the last standardisation of colour post-war whereupon black was introduced in this area.
During that period, the wheel wells were also painted Interior Green. Undercarriage legs were initially still finished in light grey, but as existing stocks of parts were used up at the factory, the overall Glossy Sea Blue finish was carried over to the undercarriage legs and wheel hubs.

Salmon
Salmon was a pale pink-coloured chromate primer used by Vought in production of the F4U Corsair. It was produced by mixing Indian Red pigment with raw Zinc Chromate primer. The actual tone was reddish orange.

As Salmon was a mixed primer, claiming an exact colour shade for it would be misleading. However, the FS colour match could be somewhere between FS 32276 and 32356.
