marines in OIF interceptor vest colour

Darryl:
If you're doing the Coyote Brown you'll have to do some mixing till you find the color you like. I think Khaki (XF-49) and Dark Yellow (Xf-60) along with some flat white are good colors to start with.

Testors Israeli Armor Sand is also a good color but will need to be lightened....

I've seen 3 different color settings for the point blank interceptor body armor.
First is 4 color woodland camo, which is widely used by our forces. I've also seen desert camo and another one in just plain tan color.
As for Tamiya paint, I think you can use black, Brown, khaki and olive drab (or army green). http://www.pointblankarmor.com/interceptor.asp# Check out this website. You can enlarge the photo of the vest.
