A few months ago, I came across a very cool-looking car. It was a 1970s-era Jeep Cherokee and it looked something like this. I’ve always been a fan of vintage Cherokees—their military-issue ruggedness appeals to the wannabe outdoorswoman in me. But this Cherokee charmed me more than most; its color was a deep, rich, super-saturated blood orange. It stood in bright contrast to the modern cars around it, whose paint jobs—pearlescent white, iridescent silver, high-gloss black—suddenly seemed to be variations on the same boring theme.
