Steve,
I've got a copy of the Pub that those Color Charts came from, that are posted elsewhere.
It came from the CF Pub: B-0L-318-009/PT-001 "Camouflage and Concealment", Annex B. Pub is dated 1978.
The Color Code for all the attached patterns is:
Olive Drab - (1)
Black (summer) or White (winter) - (2)
Green - (3)
Sorry Eric, no Pea Green listed anywhere
It then goes on to list the appendicies for each vehicle pattern, which is where the pic of the handraulicly drawn M38 with the color patterns came from.
The other Publication is B-GL-303-008/DS-001 "MARKING OF FIELD FORCE VEHICLES AND GUNS", which covers Tac Signs, Load Classification Markings etc etc. The sad thing is this stuff is too old to be found on the documentum webpage, so really, unless some Unit Library is sitting on these, I can't find the actual complete pub.
If anyone wants a pattern for one of the other vehicles, just let me know.
