Apple already has this figured out. Perhaps it's too easy to forget the iPod, but the iPod, especially the mini, nano, and shuffle all have color as a key part of the value proposition. Apple finally did that with the iPhone 5c. The most clever thing Apple did was the 5c colors with the different colored covers. Those haven't really taken off in a huge way, but I think that is in part due to the buying cycle of phones. Apple gets mass personalization in a big way. You can still get your devices engraved by Apple I believe. The only company that I've seen take a real swing at something similar is Motorola with Moto X. Too bad Google sold them.
