I remember well all the agonizing over color choices when we were all waiting on the original Roadster. (And then I ended up getting a used one in Stormtrooper White, which I never would have selected when pre-ordering, but now I love it.)

Tesla Roadster in colors
Although it's not stated on the site, he seems to have used the original Roadster's color options as his guideline.
I'm not gonna sweat it this time, though. Most likely I'll get basic black (my least favored color!) and then have it professionally vinyl-wrapped. Some folks have already been complaining about the limited color options of Model 3 and the extra cost for anything but black. Vinyl, guys! You can get almost any color and texture you can imagine. It'll protect your factory paint, and if decide after a couple of years that you'd like a color change, it's relatively cheap-and-easy to do.
