1953 is a unique color and there is debate about what is correct and what the actual color is and what variations there may be. Interior color was always unique from the exterior truck color up until the end of the A-D years when other deluxe colors became available in 1954/55. Here is where you can get a little more clarification (vendor info).

If you look at pictures of trucks you will see many where interior/exterior color is the same (my own truck is like this). That is most likely personal preference being demonstrated not factory colors.
