You can hear anything on the internet, but here's one:
The manager of the Tesla site I went to reports she was the old service manager before taking over as overall manager. She told me there were only two colors that were applied in multiple treatments. White and Red.
No idea it that's true, or how it might influence your process. How's this:
1) My wife really wanted white, I wanted red then perhaps blue. But it's for her, so she gets what she wants (when reasonable).
2) If there is any difference at this moment I can't see it, and I've looked.
3) I've spoken to a few body shops. They tell me color matching ,as in "wreckedit" can be tough. The area tesla certified body shops said "it is, but I paint several a day. We can match anything".
YMMV.
