Ok, a few questions...
Which Fletcher?? Tamiya 350th? If that's the case, then she's wearing Measure 12R which consisted of the following colors:
Haze Gray 5-H FS 35237
Ocean Gray 5-O FS 35164
Navy Blue 5-N FS 35044
Deck Blue 20-B FS 35042
Dull Black BK FS 37040
Decks are painted 20-B, as are all other horizontal surfaces. Measure 12R is a dapple pattern which is non-standard, the pattern is determined by which ship you choose.

Or, you can purchase my book: Warship Perspectives, Fletcher, Gearing and Sumner Class Destroyers in WW2, available from White Ensign, Pacific Front, Floating Drydock, etc..
