Remember that EMP only damages electronics that have a power source. Anything not plugged in or without a battery is usually safe from EMP. So even the newest car with the battery disconnected should still work after EMP. So if you have a spare vehicle sittin around you dont drive every day, disconnect the battery cables from the battery. If you want to get real serious, faraday cages protect from EMP as well, so turn your garage into a giant faraday cage and keep your essential electronics inside, unplugged and without batteries. Just thought I would add.
Also agree with the useage of neutral colors. Take for instance the ACUPAT design. A very neutral design to be used in all environments. You wont find any black on them like the old Woodland BDUs.
