Testors and Xtracolor both have made the correct shades in their enamel lines, but that does not look like much help to you. In Tamiya I suggest the following colors:
34138: xf-58 olive green or xf-26 deep green
25450: xf-23 light blue, but it needs to be lightened and grayed a bit
25526: a mix of xf-25 light sea gray and xf-23 light blue
25550: x2 white mixed with xf-23 light blue.
if you run each FS number on a websearch, you can get a computer color chip-not the most accurate way) and eyeball a match that looks right to you.
F is for FIRE, That burns down the whole town!
U is for URANIUM... BOMBS!
N is for NO SURVIVORS...
