The light blue exterior color in 1954 was Transport Blue and the dark blue exterior color in 1954 was Mariner Blue.
You will see those listed on page 2 of the document at the link I gave above and
in this Tech Tip.
The two, blue-interior colors are different color codes from either of the above exterior blues. These different interior blue code numbers might be different shades of blue or they might simply be different mixtures, including flattening compound (used with most interior colors). Maybe Greg_H will post something about the blue/blue interior color combination (that he has in his truck)?
This is 54hydramaticFL's truck. It has a dark blue exterior and a lighter blue interior.
Can you post a link to 54hydramaticFL's parts truck?
Thanks,
