I'm tossing the idea of going with a tan color for the exterior. I've been on a coyote/desert sage/Multicam kick with my gear lately and I think tan is the new od green.
Here are a few examples and quick photochops (yeah its not a 4 eye), let me know what you think. The interior would still be od green as most military vehicles are still painted that way.
