If you have been away for a while some brands only mention colors in one or two brands of paint. I listed some suggestions below for paints for a pacific fleet F4U during WW2 and Korea.
For the Pacific fleet the color is Model Masters Dark Sea Blue. Some model brands have their own paints and you will see their name.
Model masters acrylic: Dark Sea Blue #4686
Model masters enamil: Dark Sea Blue #1717
Testors little bottle enamil gloss: Dark Blue gloss 1111TT
Testors little bottle enamil flat: Flat Sea Blue 1127TT (mix in some gloss base)
Humbrol #77 Navy blue (mix in gloss base)
Edit:
A Revell kit. The colors are going to be listed in Revell's own paint line.
