This is one of many questions in modeling that seems to pop up rather frequently.  My understanding is, as Dana Bell says in his reply, that the letters are blue so that's what I go with...but since decal manufacturers have done both blue and black everyone can choose which color they prefer.

I went to see the P-38 that was dug out of the ice in Greenland.
This was during its rebuild in Middlesboro, Kentucky.
I looked really hard at the "US ARMY" letters and it appeared to be a very, very dark blue.
My two cents anyway...
