Digital's cool. A guy on MIVE painted his Audi like that. Not sure how long it took. Actually, it is probably a vinyl wrap. That would be the easiest way to go if you're doing something complicated. And believe me, I should have wrapped the Probe.
That lozenge paint job is pretty cool looking but you'd ALWAYS have people asking why your car has scales, if it's a snake, if it's a lizard, etc. It would get annoying.
The highest visibility color to humans is safety green. Our retinas are more sensitive to that specific shade than any other wavelength. That's why they paint it onto fire trucks.
Of course you could combine that with the military thing by doing a Korean war era F86 Sabre paint job. Just make the stripes out of reflective green and you're good to go.
